A box that has a length of 2x + 2 and width of x - 2 has a perimeter of 90 centimeters. If the height of the box is x, what is the volume of the box?

First find the value of X from the perimeter given

Perimeter = L*W

90 = 2 ((2x+2) + (x-2))

90 = 4x + 4 + 4x - 4

90 = 8x

x = 11.25

Length = 2x + 2

2 (11.25) + 2

=24.5

Width = x-2

11.25 - 2

=9.25

h = x

= 11.25

Volume = L*W*H

24.5 * 9.25 * 11.25
