What Is The Surface Area Of this triangular prism? The Base Of Each Triangle 42m And the height of the triangular base is 20m. (
ehidna [41]

Answer:

The surface area is 2,440\ m^{2}

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The surface area of a triangular prism is equal to

SA=2B+PH

where

B is the area of the triangular base

P is the perimeter of the triangular face

H is the height of the prism

<em>Find the area of the base B</em>

B=\frac{1}{2}(42)(20)=420\ m^{2}

<em>Find the perimeter of the base P</em>

P=(42+29+29)=100\ m

we have

H=16\ m

substitute the values

The surface area is

SA=2(420)+100(16)=2,440\ m^{2}
