Answer:
[tex]Area = 346m^2[/tex]
Step-by-step explanation:
Given
[tex]Length = 5m\\Width = 6m\\Height = 13m[/tex]
Required
Determine the surface area
This is calculated as:
[tex]Area = 2 * (Length * Width + Length * Height + Width * Height)[/tex]
So, we have:
[tex]Area = 2 * (5m * 6m + 5m * 13m + 6m * 13m)[/tex]
[tex]Area = 2 * (30m^2 + 65m^2 + 78m^2)[/tex]
[tex]Area = 2 * (173m^2)[/tex]
[tex]Area = 346m^2[/tex]
