Question

17. A rectangular prism has a length of 12 cm, a

height of 6/cm, and a width of 4 cm. Use the
formula SA = 2({w) + 2(wh) +2(ehy to find the
surface area of the rectangular prism.

Answer 1

SA = 288 cm

Explanation:

l = 12

w = 4

h = 6

SA = 2lw + 2wh + 2lh

SA = (2 x 12 x 4) + (2 x 4 x 6) + (2 x 12 x 6)

SA = 96 + 48 + 144

SA = 288
