Question

Find the total area of the prism.

Answer 1

`\boxed{\mathrm{864 \: in^2}}`

Explanation:

The shape is a cube.

Apply formula for total surface area of cube.

`SA=6a^2`

`SA=\mathrm{total \: surface \: area}\\ a =\mathrm{side \: length}`

`SA=6(12)^2`

`SA=6(144)`

`SA=864`

Answer 2

`\boxed{Area = 144 inches^2}`

Explanation:

Area of a cube = Volume/Length

Where Length = 12 inches, Volume = 1728

Area = 1728/12

Area = 144 inches^2
