Question

Find the total surface area of the rectangular prism in square millimeters. 2cm 6 cm 9cm

Answer 1

Answer:  168 square cm

==============================================

Work Shown:

• L = 2 = length
• W = 6 = width
• H = 9 = height

The order of length, width and height doesn't matter

SA = surface area of rectangular prism

SA = 2*(LW + LH + WH)

SA = 2*(2*6 + 2*9 + 6*9)

SA = 2*(12 + 18 + 54)

SA = 2*(30+54)

SA = 2*(84)

SA = 168 square cm
