Question

How many square inches of gift wrap will be needed to cover a box that is 5in x 7in x 3in?

Answer 1

Answer: 142 squared inches of gift wrap

Explanation:

To find how many square inches of gift wrap you would need, you would use the formula for the surface area of the box (rectangle)

• Formula: 2 ( length x width + width x height + height x length ) = Surface Area

Now plug the numbers in from the given dimensions

• 2 ( 7 x 5 + 5 x 3 + 3 x 7 ) = Surface Area

Now solve...

• 2 ( 7 x 5 + 5 x 3 + 3 x 7 ) = 142

Giving you the answer of 142 squared inches of gift wrap

Hope this is correct and helpful! ^^

Answer 2

65 sq.inches

Explanation:

To find the total surface area of a box, you need to calculate the area of each of its faces and add them together. In this case, the box has three faces with dimensions 5 inches by 7 inches, and three faces with dimensions 5 inches by 3 inches.

The total surface area of the box is therefore:

(5 * 7) * 2 + (5 * 3) * 2 = 35 + 30 = 65 square inches

This means that you will need 65 square inches of gift wrap to cover the box.

Hope this helps you
