What is the total surface area of the rectangular prism in square inches?

Answer 1

272 square inches

Explanation:

Given

`l = 8` --- length

`w = 2` --- width

`h = 12` ---- height

Required

Determine the total surface area (SA)

This is calculated using:

`SA = 2 * (lw + wh + lh)`

`SA = 2 * (8*2+2*12+8*12)`

`SA = 2 * 136`

`SA = 272`

The total surface area is 272 square inches
