Answer:
![1706.67 feet](https://img.qammunity.org/2021/formulas/mathematics/high-school/yp19u2tah2io6916hzceauoamjfsy3ho33.png)
Explanation:
Formula: Volume =
![(1)/(3) \alpha^(2)h](https://img.qammunity.org/2021/formulas/mathematics/high-school/7pg71rh568v16mree1ytn3nmrfzy428sxr.png)
a is the length of the base's edge and h is the height. Since 16 is the length we would square it as it is the length, then we would multiply it by the height which is 20 ft.
Steps: Multiply
Volume =
![(1)/(3) \alpha^(2)h](https://img.qammunity.org/2021/formulas/mathematics/high-school/7pg71rh568v16mree1ytn3nmrfzy428sxr.png)
=
![(1)/(3) * 16^(2) * 20](https://img.qammunity.org/2021/formulas/mathematics/high-school/vgmkuo99lqtwzizpcps6yuaqkc4blvlbjc.png)
=
