The sand we need to fill the cylinders is equal to the total volume of the six cylindrical posts .

Given terms ( common for each cylinder ) :

  • height (h) = 4 ft
  • radius. (r) = 0.5 ft

\large \boxed{ \mathrm{volume =\pi {r}^{2}  h}}

  • 3.14 \times  \dfrac{1}{2}  \times   \dfrac{1}{2}  \times 4

  • \mathrm{3.14 \: ft {}^{3} }

Since volume of each cylinder is equal, so total volume of six cylindrical post :

  • 3.14 \times 6

  • { \mathrm{18.84 \: ft {}^{3} }}
