Find the surface area of a rectangular prism whose length is 18 millimeters, height is 10 millimeters, and width is 2 millimeters.(1 point)
mm2
and its NOT 436
The formula to find the surface area of a rectangular prism is 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height.
Plugging in the values:
2(18)(10) + 2(18)(2) + 2(10)(2)
360 + 72 + 40
= 472 mm²
Therefore, the surface area of the rectangular prism is 472 mm².
