Question

Find the surface area of the prism.

Answer 1

`A=202\ cm^2`

Explanation:

Given that,

The dimensions of the prism are 4 cm, 9 cm and 5 cm respectively.

The formula for the surface area of the prism is given by :

`A=2(lb+bh+hl)`

Put all the values,

`A=2(4(9)+9(5)+5(4))\\\\A=2(36+45+20)\\\\A=202\ cm^2`

So, the required surface area of the prism is equal to
`202\ cm^2`.
