Answer:

  • 326.6 square inches
  • 3402 square feet

Explanation:

The net will be a rectangle representing the lateral area. Its length will be 2π(4 in), the circumference of the box, and its height will be 9 in, the height of the box. On either side of that rectangle will be an 8-in diameter circle representing the ends of the box.

The total surface area is given by the formula ...

SA = 2πr(r +h)

For one box, the area is ...

SA = 2(3.14)(4 in)(4 in +9 in) ≈ 326.6 in² . . . . area of one box

__

There are 144 square inches in a square foot, so the area required for 1500 boxes is ...

(1500)(326.56 in²)/(144 in²/ft²) ≈ 3402 ft² . . . area of 1500 boxes
