Answer
Final volume= 8474 $m^{3}$
Work Step by Step
The volume of a cube is given by the formula
V=$(4s)^{3}$
The volume of a cylinderis given by the formula
V=$\pi s^{2} \times$ h and since h=48 we get the formula
$\pi s^{2} \times$ 48
Thus,
Final volume= Volume of cube-volume of cylinder
Final volume= V=$(4s)^{3}$ - $\pi s^{2} \times$ 48
Given that the 15=s we plug it into the equation to get the final volume.
Final volume= V=$(4(15))^{3}$ - $\pi (15)^{2} \times$ 48
Final volume= 8474 $m^{3}$
