A diagram represents a gift box whose length is 20 cm width is 15 cm and height is 12 cm jomo wants to wrap the gift box how many squared centimeters of wrapping paper is needed to cover the box completely?

Answer 1

To find the amount of wrapping paper needed to cover the gift box completely, we need to calculate the surface area of the box.

The surface area of a rectangular prism (gift box) is given by the formula:

Surface Area = 2lw + 2lh + 2wh

where l = length, w = width, and h = height of the box.

Substitute the given values into the formula:

Surface Area = 2(20*15) + 2(20*12) + 2(15*12)
Surface Area = 2(300) + 2(240) + 2(180)
Surface Area = 600 + 480 + 360
Surface Area = 1440

Therefore, the total surface area of the gift box is 1440 square centimeters. So, Jomo would need 1440 square centimeters of wrapping paper to cover the box completely.
