Question

A box without a top is made from a rectangular piece of cardboard, with dimensions 25 inches by 20 inches, by cutting out square corners with side length x inches. which expression represents the volume of the box in terms of x?

Answer 1

`x(20-2x)(25-2x)`

Explanation:

The length removed from each side is
`2x`.

So, the length and width of the box are
`25-2x` and
`20-2x`.

The height of the box is
`x`, so the volume is
`x(20-2x)(25-2x)`.
