Petra fills a small cardboard box with sand. The dimensions of the box are 3 inches by 4 inches by 2 inches. Petra decides to cover the box by gluing on wrapping paper. How much wrapping paper does she need to cover all six sides of the box?

24 in

Step-by-step explanation:

3 x 4 x 2

(We are assuming that this is for the volume of the whole box.)

3 x 4 = 12

12 x 2 = 24

24 in for the whole volume of this box.

In case you are figuring out the measurements for one side:

24/6 = 4

4 in for one side.

And, if that is for just 4 sides, then you would multiply by 2 more.

So:

3 x 4 x 2 x 2

24 x 2 = 48 in     If the original formula was for just 4 sides.

step-by-step explanation:

107 units
