- Find the volume of the right square pyramid:
**A.**450 cm^{3}**B.**500 cm^{3}**C.**1,500 cm^{3}**D.**150 cm^{3} - Find the volume:
**A.**960 mm^{3}**B.**480 mm^{3}**C.**120 mm^{3}**D.**840 mm^{3}

## Answers and explanations

- The correct answer is
**Choice (B).**The formula for the volume of a pyramid is

where

*B*is the area of the pyramid's base and*h*is the pyramid's height. You're dealing with a right square pyramid, so the base is a square. Because a square has an area of*A*=*s*^{2}(where*s*is the length of one side of the base), you can write the formula asReplace the variables with the numbers you know:

- The correct answer is
**Choice (A).***V*=*lwh*, with*l*representing length,*w*representing width, and*h*representing height:
