Question

what is the surface area for a m rectangular prism. with the measurements as: height = 9 length = 3width = 7

Answer 1

Surface area = 222 square cm

Step-by-step explanation:

Given the following data

Length = 3 cm

Height = 9 cm

Width = 7 cm

Surface area = 2(wl + hl + hw)

Surface area = 2(7 * 3 + 9 * 3 + 9 * 7)

Surface area = 2( 21 + 27 + 63)

Surface area = 2( 111)

Surface area = 222 square cm

Therefore, the surface area is 222 square cm
