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 :

$3.14 \times 6$

${ \mathrm{18.84 \: ft {}^{3} }}$
