What Is The Surface Area For A M Rectangular Prism With The Measurements As Height 9 Length 3width 7 class=

Answer :

Answer:

Surface area = 222 square cm

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
