Answer:
The surface area of prism = 352 square inches
Step-by-step explanation:
Formula:-
Surface are of rectangular prism = 2(lb + bh + lh)
l - Length of prism
b - width of prism
h - Height of prism
It is given that,a rectangular prism measures 8 inches in width, 12 inches in length, and 4 inches in height.
To find the surface area of prism
l = 12 inches
b = 8 inches
h = 4 inches
surface area = 2(lb + bh + lh) = 2(12*8 + 8*4 +12*4)
= 2(96 + 32 + 48) = 352 square inches.
Therefore the surface area of prism = 352 square inches
