Question

A metal product company is coating the outside of the special microwave in the box shown. Find the area that needs to be coated

Answer 1

The surface area of a box = * (length * height) + 2 * (width * height)

h = 3 w = 9 l = 13

2 * (13 * 9) + 2 * 39 + 2 * 27 in^2

234 + 78 + 54 = 366 in^2

A = 366 in^2
