Question

Find the area of the entire surface of the prism 8.

Answer 1

Surface area of a rectangular prism:

`SA=2l*w+2w*h+2l*h`

l is the length

w is the width

h is the height

For the given rectangular prism:

`\begin{gathered} l=2yd \\ w=4yd \\ h=5yd \\ \\ SA=2*2yd*4yd+2*4yd*5yd+2*2yd*5yd \\ SA=16yd^2+40yd^2+20yd^2 \\ SA=76yd^2 \end{gathered}`Then, the surface area of the given rectangular prism is 76 square yards
