A company produces cardboard boxes with the top, bottom and sides measuring 5 feet. It costs the company 4 cents a square foot to make each box. The square footage is determined by finding the area of all six sides of the box. Find the cost to make 100 boxes.

Answer 1

A side has 5x5=25 square feet.
A box has 6 sides.
6 x 25 = 150 square feet.
4 cents per foot :
150 x 4 = 600 cents = $6 per boxes

100 boxes : 6 x 100 = 600$ total.

Those are some costly boxes. Then again, they are very big boxes.
