this is a question on a review assignment that i’m stuck on , my summer school teacher said i could get help if i needed. any help would be greatly appreciated

Answer:
volume = 3549.203
Step-by-step explanation:
you need to subtract the volume of the cylinder from the volume of the box
cylinder:
[tex]vol=\pi r^2h\\V=\pi (5)^2(20)\\V=\pi (25)(20)\\V=500\pi[/tex]
box:
[tex]vol=(length)(width)(height)\\V=(20)(16)(16)\\V=5120[/tex]
subtract:
[tex]5120-500\pi =3549.203[/tex]
