The expression represents the surface area of the prism is 2.24+120+160+200. Therefore, option B is the correct answer.
Here a triangular prism has been provided with some measurements.
We have to find Which expression can be used to find the surface area of the following triangular prism.
The formula for the surface area of a triangular prism is formed by adding up the area of all the rectangular and triangular faces of a prism. Observe the following figure of a triangular prism to know the dimensions that are considered to frame the formula.
Surface area = (Perimeter of the base × Length of the prism) + (2 × Base Area) = (S1 +S2 + S3)L + bh
Here, S1, S2 and S3 are sides of triangles, l=length of the prism, b=base and h=height.
Now, (6+8+10)20+8×6=120+160+200+48
=2.24+120+160+200
The expression represents the surface area of the prism is 2.24+120+160+200. Therefore, option B is the correct answer.
