Answer:
240 ft²
Explanation:
The number of square feet needed is equal to the lateral surface. So, it can be calculated as:
[tex]A=2(l+w)h[/tex]Where l is the length, w is the width and h is the height.
Then, replacing l by 10 ft, w by 10 ft, and h by 6ft, we get:
[tex]\begin{gathered} A=2(10+10)\cdot6 \\ A=2(20)\cdot6 \\ A=40\cdot6 \\ A=240 \end{gathered}[/tex]Therefore, the answer 240 ft²
