Answer 1

`Area = 395.2cm^2`

Explanation:

Given

The attached prism

Required

The surface area

This is calculated as:

`Area= 2(LW + LH + WH)`

Where:

`Length \to L=5.78`

`Width \to W=12.7`

`Height \to H=6.72`

So, we have:

`Area = 2(5.78 * 12.7 + 5.78 * 6.72 + 12.7 * 6.72)`

Using a calculator, we have:

`Area = 395.1832`

`Area = 395.2cm^2` ---- approximated
