How many square feet in a box 4.5 inches by 10.5 inches by 23 inches?

Answer 1

The box has three pairs of sides.

One pair of sides: 4.5 x 10.5 = 47.25 square inches = 0.328125 square foot each

Another pair of sides . . . 4.5 x 23 = 103.5 square inches = 0.71875 square foot each

The third pair of sides . . . 10.5 x 23 = 241.5 square inches = 1.677 square foot each

So, if you have to paint the box or cover it with carpet, you need to cover 5.448 square feet.
