Question

Find the surface area 7in 8in 16in​

Answer 1

`S = 592\ in^2`

Explanation:

Step 1: Determine important information

Using the given numbers it doesn't really matter which is which because the equation multiplies everything together.

Surface Area of a Rectangular Prism →
`S= 2(wl+hl+hw)`

Step 2: Plug in the values and solve

`S = 2((7\ in * 8\ in) + (16\ in * 8\ in) + (16\ in * 7\ in))`

`S=2(56\ in^2 + 128\ in^2 + 112\ in^2)`

`S = 2(296\ in^2)`

`S = 592\ in^2`

Answer:
`S = 592\ in^2`
