<h3>Surface area of the prism is 724 square centimeters</h3>
<em><u>Solution:</u></em>
The surface area of prism is given as:

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
<em><u>Find area of base</u></em>

<em><u>Find the perimeter of the base P</u></em>

<em><u>Find the surface area SA</u></em>

Thus the surface area of the prism is 724 square centimeters
