A rectangular prism that is 1 inch high, 2 inches wide, and 3 inches long. What is the surface area?
Answer provided by our tutors
let
h = 1 in the height of the prism
w = 2 in the width of the prism
l = 3 in the length of the prism
the surface are is
A = 2 (lw + lh + wh)
A = 2(3*2 + 3*1 + 2*1)
A = 2(6 + 3 + 2)
A = 22 in^2
the surface area of the prism is 22 square inches.
