Question

Gary wrapped a cube shaped gift box with wrapping paper.The box was 8 inches long.What was the minimum amount of paper Gary could have used to cover the box?

Answer 1

If it's a cube, each side (6 sides) is 8x8. So 8x8 is 64, 64 times 6 is 384 square inches. Does that seem right to you??

Answer 2

First, a cube have six planes (see photo attached). We can then see the box is wrapped by 6 squares, which have the same length. In this case, 8 inches.

We can then find out the area of a square:

8 x 8

=64 sq. inch

To find the total amount of paper, we multiply the area of a square by 6:

64 x 6

=384 sq.inch

Therefore the answer is 384 sq.inch.

Hope it helps!
