Find the surface area of a rectangular prism whose length is 18 millimeters, height is 10 millimeters, and width is 2 millimeters. (1 point)
To find the surface area of a rectangular prism, you need to calculate the area of each face and add them together.
The formula for the surface area of a rectangular prism is:
2lw + 2lh + 2wh
Given the dimensions:
l = 18 mm
h = 10 mm
w = 2 mm
Substitute the values into the formula:
2(18)(10) + 2(18)(2) + 2(10)(2)
= 360 + 72 + 40
= 472
Therefore, the surface area of the rectangular prism is 472 square millimeters.
