First, we find the cube volume:

Volume = (a)^3 = (8in)^3 = 512in^3

Then, we find the right cylinder volume


\begin{gathered} V=\text{ }\pi r^2h=\text{ }\pi(4in^)^2(8in)\text{ = 16in}^2(8in)(\pi) \\ =\text{ 402.12 in}^3 \end{gathered}

So, the remaining volume will be: 512in3 - 402-12in3 = 109.88in^3

≈ 110 in^3
