What is the formula for the volume of a rectangular prism?
length × width × height
length + width + height
2(length × width + width × height + height × length)
length × width
The volume of a rectangular prism is found by multiplying its length, width, and height. This formula calculates the space occupied inside the prism.
What is the volume formula for a cube?
side³
3 × side
side²
4/3 × side³
A cube has all sides equal, so its volume is calculated by raising the side length to the third power. This represents the product of its length, width, and height.
Which expression represents the volume of a cylinder with radius r and height h?
πr²h
2πrh
πrh²
πr³h
The volume of a cylinder is obtained by multiplying the area of its circular base (πr²) by its height. This formula gives the total space inside the cylinder.
Which of the following is the appropriate unit for measuring volume?
cubic centimeters
meters per second
kilograms
volts
Volume is measured in cubic units, such as cubic centimeters or cubic meters. These units indicate the three-dimensional space occupied by an object.
If each side of a cube is doubled, by what factor does its volume increase?
8
4

When linear dimensions of a cube are doubled, the volume increases by a factor of 2³, which is 8. This demonstrates the cubic relationship between side length and volume.
What is the formula for the volume of a cone with radius r and height h?
(1/3)πr²h
πr²h
(1/2)πr²h
2πr²h
A cone's volume is one-third of the volume of a cylinder with the same base and height. Therefore, the formula is (1/3)πr²h, which accounts for the tapering shape of a cone.
Which of the following formulas correctly represents the volume of a sphere with radius r?
(4/3)πr³
πr²
2πr³
(1/3)πr³
The volume of a sphere is given by the formula (4/3)πr³, derived from integral calculus. This formula calculates the space occupied by a sphere based on its radius.
A composite solid consists of a cylinder with radius r and height h, topped by a hemisphere of the same radius. What is the expression for its total volume?
πr²h + (2/3)πr³
πr²h + (4/3)πr³
(1/3)πr²h + (2/3)πr³
πr²h + πr³
The volume of the composite solid is the sum of the cylinder's volume (πr²h) and the hemisphere's volume ((2/3)πr³). The hemisphere's volume is half that of a sphere.
What is the formula for the volume of a pyramid with base area B and height h?
(1/3)Bh
Bh
(1/2)Bh
(1/4)Bh
The volume of a pyramid is calculated by taking one-third of the product of its base area and height. This formula reflects the tapering shape of a pyramid compared to a prism.
How do you calculate the volume of a triangular prism if the area of its triangular base is A and its length is L?
A × L
½A × L
A + L
2A × L
The volume of a prism, including a triangular prism, is found by multiplying the area of the base by the length (or height) of the prism. This formula applies regardless of the base being triangular.
If all dimensions of a solid shape are scaled by a factor of k, by what factor does its volume scale?
k³
k²
k

Volume is a three-dimensional measure, so if each dimension is scaled by a factor of k, the volume is multiplied by k³. This demonstrates the cubic relationship in scaling.
A cylindrical water tank has a radius of 5 meters and a height of 10 meters. What is its volume?
250π cubic meters
50π cubic meters
500π cubic meters
150π cubic meters
To calculate the volume of a cylinder, use πr²h. Here, r² = 25 and h = 10, so the volume is π × 25 × 10 = 250π cubic meters.
How many cubic centimeters are there in one cubic meter?
1,000,000
100,000
10,000
1,000
Since 1 meter equals 100 centimeters, one cubic meter is 100³ = 1,000,000 cubic centimeters. This conversion is important for unit consistency in volume measurements.
A cylinder has a volume of 300π cubic centimeters and a height of 10 centimeters. What is the radius of this cylinder?
√30 centimeters
30 centimeters
10√3 centimeters
√10 centimeters
Using the formula V = πr²h, substitute V = 300π and h = 10 to get πr²×10 = 300π. Dividing both sides by 10π gives r² = 30, so r = √30 centimeters.
A sphere's volume is increased by a factor of 27. By what factor does its radius increase?
3
9
27
81
Since the volume of a sphere is proportional to the cube of its radius, if the volume increases by 27, the radius increases by the cube root of 27, which is 3. This illustrates the cubic relationship between radius and volume.
A composite solid consists of a cube with side length a and a right square pyramid attached to one face of the cube with a base side length of a and height h. What is the formula for the total volume?
a³ + (1/3)a²h
a³ + a²h
(1/3)a³ + a²h
a³ + (1/2)a²h
The volume of the composite solid is the sum of the cube's volume, which is a³, and the pyramid's volume, given by (1/3) times the area of its base (a²) times its height h. This combination reflects the addition of two distinct solid volumes.
A conical tank with a radius of 4 meters and height of 9 meters is completely filled with water. How much water does it hold?
48π cubic meters
36π cubic meters
72π cubic meters
108π cubic meters
The volume of a cone is calculated as (1/3)πr²h. Substituting r = 4 and h = 9 gives (1/3) × π × 16 × 9 = (1/3) × 144π = 48π cubic meters. This represents the total volume of water in the tank.
Given a sphere with a volume of 36π cubic centimeters, what is its radius?
3 centimeters
4 centimeters
2 centimeters
6 centimeters
The volume of a sphere is given by (4/3)πr³. Setting this equal to 36π and solving yields r³ = (36π × 3)/(4π) = 27, so r = 3 centimeters. This involves reversing the volume formula to find the radius.
A frustum of a right circular cone has a volume given by V = (1/3)πh(R² + Rr + r²). If the top radius r is 3, the bottom radius R is 6, and the height h is 4, what is its volume?
84π cubic centimeters
72π cubic centimeters
96π cubic centimeters
100π cubic centimeters
Substitute the values into the frustum formula: V = (1/3)π × 4 × (6² + 6×3 + 3²) = (4/3)π × (36 + 18 + 9) = (4/3)π × 63 = 84π cubic centimeters. This calculation shows the correct application of the formula.
An architect designs a sculptural fountain composed of a cylinder with a hemispherical top and a conical cavity carved out from the cylinder's base. If the cylinder has radius r and height h, and the conical cavity has height h/2, what is the expression for the net volume of the fountain?
(5/6)πr²h + (2/3)πr³
πr²h + (2/3)πr³ - (1/3)πr²h
πr²h + (2/3)πr³
(1/2)πr²h + (2/3)πr³
The net volume is determined by adding the volume of the cylinder (πr²h) and the hemispherical top ((2/3)πr³), then subtracting the volume of the conical cavity. The cavity's volume is (1/3)πr² × (h/2) = (1/6)πr²h, so the net volume simplifies to (5/6)πr²h + (2/3)πr³.
