Question

A rectangular prism has a volume of 729 ft3. The length, width, and height are all the same What is the length of each side of the prism?

Answer 1

The formula for volume is length×width×height (lwh). So if the length, width and height are the same, then the measurement of each is the cube root of 729:

`x * x * x = 729 \\ {x}^(3) = 729 \\ x = 9`
So the length of each side of the prism is 9ft
