Question 801852: Constructing a Box. A box is constructed from a rectangular piece of metal by cutting squares from the corners and folding up the sides. The square, cutout corners are x inches by x inches.

2. Suppose that the dimensions of the metal piece are 20 inches by 30 inches.
a. Write a polynomial expression that gives the volume of the box.
b. Find the volume of the box for x = 4.

You can put this solution on YOUR website!
a) Volume of box = (20 - 2x)(30 - 2x)x
b) Volume of box = (20 - 8)(30 - 8) *4
Volume of box = (12)(22)4
Volume of box = 1056 inches^3
Hope htis helps.
