Surface area of the prism is 724 square centimeters
Solution:
The surface area of prism is given as:
[tex]Surface\ Area = 2B+PH[/tex]
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
[tex]B = LW\\\\B = 12 \times 11\\\\B = 132[/tex]
Find the perimeter of the base P
[tex]P=2(L+W)\\\\\ P=2(12+11)=46\ cm[/tex]
Find the surface area SA
[tex]Surface\ Area =2(132)+(46)(10)\\\\Surface\ Area = 724\ cm^{2}[/tex]
Thus the surface area of the prism is 724 square centimeters
