Find the surface area of a rectangle or prism whose length is 18 mm height is 10 mm and width is 2 mm

Answer 1

The surface area of a rectangular prism can be calculated using the formula:

2lw + 2lh + 2wh

Given that the length (l) is 18 mm, height (h) is 10 mm, and width (w) is 2 mm, we can substitute these values into the formula:

2(18)(2) + 2(18)(10) + 2(2)(10)
= 72 + 360 + 40
= 472 mm²

Therefore, the surface area of the rectangular prism is 472 mm².
