Answer 1

To find the surface area of a rectangular prism you use the next formula:

`SA=2lw+2wh+2lh`

l is length

w is width

h is height

For the given prism:

l=5yd

w=4yd

h=8yd

`\begin{gathered} SA=2(5yd)(4yd)+2(4yd)(8yd)+2(5yd)(8yd) \\ SA=40yd^2+64yd^2+80yd^2 \\ SA=184yd^2 \end{gathered}`

The surface area of the given rectangular prism is 184 square yards
