Find the surface area of a rectangular prism whose length is 18 millimeters, height is 10 millimeters, and width is 2 millimeters.
The surface area of a rectangular prism is given by the formula: SA = 2lw + 2lh + 2wh, where l is the length, h is the height, and w is the width of the prism.
Plugging in the values given in the problem, we get:
SA = 2(18 x 2) + 2(18 x 10) + 2(2 x 10)
SA = 72 + 360 + 40
SA = 472
Therefore, the surface area of the rectangular prism is 472 square millimeters.
