Answer:
1675.52 cubic meters.
Explanation:
First, we establish that the maximum amount of sand that can be stored in the structure is the volume of the conical structure.
![\text{Volume of a Cone }= (1)/(3)\pi r^2 h$ where: \left\{\begin{array}{ll}$r=Base radius\\$h=height of the cone\\-----\\r=10m\\h=16m\end{array}\right](https://img.qammunity.org/2021/formulas/mathematics/college/3qvdgdrtsumc4yuzuiy8gq798sau95yolw.png)
Therefore:
![\text{Volume of the structure}= (1)/(3)\pi * 10^2 * 16\\=(1600\pi)/(3) $ cubic meters\\\approx 1675.52$ m^3 $(correct to 2 d.p)](https://img.qammunity.org/2021/formulas/mathematics/college/3z7cq89lytqu8rnxhrfrdjefdhk5e1x8b0.png)
The maximum amount of sand that can be stored in the structure is 1675.52 cubic meters.
