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
