Question

A net and the prism it will form when it is folded are shown below.

Answer 1

Surface area of the prism is 724 square centimeters

Solution:

The surface area of prism is given as:

$Surface\ Area = 2B+PH$

where

B is the area of the base

P is the perimeter of the base

H is the height of the prism

L = 12 cm

W = 11 cm

H = 10 cm

Find area of base

$B = LW\\\\B = 12 \times 11\\\\B = 132$

Find the perimeter of the base P

$P=2(L+W)\\\\\ P=2(12+11)=46\ cm$

Find the surface area SA

$Surface\ Area =2(132)+(46)(10)\\\\Surface\ Area = 724\ cm^{2}$

Thus the surface area of the prism is 724 square centimeters
