Answer:

The surface area of the rectangular prism is of 22 square millimeters.

Explanation:

Surface area of rectangular prism:

The surface area of a rectangular prism with length l, width w and height h is given by:


S = 2(lw + lh + wh)

Length 12 mm, width 3mm and height 5 mm

This means that
l = 12, w = 3, h = 5

Surface area:


S = 2(lw + lh + wh) = 2(12(3) + 12(5) + 3(5)) = 2(36 + 60 + 15) = 2(111) = 222

The surface area of the rectangular prism is of 22 square millimeters.
