Answer:

[tex]Area = 395.2cm^2[/tex]

Step-by-step explanation:

Given

The attached prism

Required

The surface area

This is calculated as:

[tex]Area= 2(LW + LH + WH)[/tex]

Where:

[tex]Length \to L=5.78[/tex]

[tex]Width \to W=12.7[/tex]

[tex]Height \to H=6.72[/tex]

So, we have:

[tex]Area = 2(5.78 * 12.7 + 5.78 * 6.72 + 12.7 * 6.72)[/tex]

Using a calculator, we have:

[tex]Area = 395.1832[/tex]

[tex]Area = 395.2cm^2[/tex] ---- approximated
