A square piece of cardboard has a perimeter of 32 inches. How long is each side?

8 inches

Step-by-step explanation:

All the sides of a square are equal so to find the side you can divide the perimeter by 4.

32 / 4 = 8

here you go

Step-by-step explanation:

An open box is to be made from a square piece of cardboard, 32 inches on a side, by cutting equal squares with sides of length x from the corners and turning up the sides (see figure below). Determine the function, V, in terms of x, that represents the volume of the box.

A. -2x^3+32x^2

B.-4x^3+64x^2

C.4x^3-64x^2+32x

D.-4X^3+64x^2-32x

E.4x^3-128x^2-1024x =volume = x(32-2x)^2
