What is the surface area of a rectangular prism
10in
3in
9in
To find the surface area of a rectangular prism, use the formula:
2lw + 2lh + 2wh
where l = length, w = width, and h = height.
Given the dimensions of the rectangular prism:
l = 10in, w = 3in, h = 9in
Substitute the values into the formula:
2(10)(3) + 2(10)(9) + 2(3)(9)
= 60 + 180 + 54
= 294
Therefore, the surface area of the rectangular prism is 294 square inches.
