Question

What is the surface area of a rectangular prism with length 13mm, width 2mm, and height 7mm?

44mm(to the 2nd power)
132mm(to the 2nd power)
182(to the 2nd power)
262mm(to the 2nd power)

Answer 1

is there any picture of the dimensions
rough diagram

Answer 2

using the formula SA = 2bh + 2bw + 2hw
b = 13
w = 2
h = 7
SA = 2(13)(7) + 2(13)(2) + 2(7)(2)
SA = 182 + 52 + 28
SA = 262
Then we add the mm since that is the one were using and the ^2 because it is a surface area.
Answer 262 mm^2
