Find the volume of the rectangular prism.

First, we must know that we can find the volume of a prism using the formula

Volume = length × width × height

Since we are finding the volume of a cube, all the sides will be the same length so we can represent this as Volume = .

Now, we can substitute in our values. It does not matter where the numbers go because they are all the same.

7.5 × 7.5 × 7.5 = 421.875

Therefore, the volume of the prism is 421.875

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
