Answer:
[tex]A = 592\,ft^{2}[/tex]
Step-by-step explanation:
The surface area of a rectangular prism is given by this formula:
[tex]A = 2\cdot w\cdot h + 2\cdot w \cdot t + 2\cdot h \cdot t[/tex]
Where:
[tex]w[/tex] - Width, in feet.
[tex]h[/tex] - Height, in feet
[tex]t[/tex] - Thickness, in feet.
Finally, the surface area is computed by replacing every variable:
[tex]A = 2\cdot (10\,ft)\cdot (8\,ft) + 2\cdot (10\,ft)\cdot (12\,ft) + 2\cdot (8\,ft)\cdot (12\,ft)[/tex]
[tex]A = 592\,ft^{2}[/tex]
