Question

How many fence material is needed to make a dog pen which measures 10ft by 10ft and is 6ft high

Answer 1

240 ft²

Step-by-step explanation:

The number of square feet needed is equal to the lateral surface. So, it can be calculated as:

`A=2(l+w)h`

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:

`\begin{gathered} A=2(10+10)\cdot6 \\ A=2(20)\cdot6 \\ A=40\cdot6 \\ A=240 \end{gathered}`

Therefore, the answer 240 ft²
