The volume of a rectangular prism:

[tex]V_p=Bh\\\\B=wl\\\\w=2\ in;\ l=3\ in;\ h=9\ in[/tex]

substitute

[tex]V_p=2\cdot3\cdot9=54\ in^3[/tex]

The volume of a cylinder:

[tex]V_c=\pi r^2h\\\\r=1.5\ in;\ h=8\ in[/tex]

substitute:

[tex]V_c=\pi\cdot(1.5)^2\cdot8=\pi\cdot2.25\cdot8=18\pi\ in^3\approx18\cdot3.14=56.52\ in^3[/tex]

Answer: C. The cylinder has the greater volume.
