Find the surface area of the rectangular prism with l= 12.5 m, w= 16.5 m, and h= 5.5 m.
My Answer )1134.375
(I'm having doubys about my answer , is it correct ?)
surface area
= 2lw + 2lh + 2wh
= NOT 1134.375 , I get 731.5
Thanks , i knew something was wrong !! lol
@100% Your a liar you C&P that one 3 other questions
To find the surface area of a rectangular prism, we need to calculate the area of each of its six faces and then sum them up.
The formula for 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.
In this case, the length (l) is 12.5 m, the width (w) is 16.5 m, and the height (h) is 5.5 m.
Using the formula, we can compute the surface area:
2lw + 2lh + 2wh = 2(12.5)(16.5) + 2(12.5)(5.5) + 2(16.5)(5.5)
= 412.5 + 137.5 + 181.5
= 731.5 m^2
So, the correct surface area of the rectangular prism is 731.5 square meters, not 1134.375 square meters.
