Volume of the cylinder:
[tex]v = \pi {r}^{2} h[/tex]
[tex]v = 3.14 \times {4}^{2} \times 5[/tex]
[tex]v = 251.2 \: {cm}^{3} [/tex]
Volume of the rectangular prism:
[tex]v = lwh[/tex]
[tex]v = 12 \times 8 \times 4[/tex]
[tex]v = 384 \: {cm}^{3} [/tex]
Total volume:
[tex]v = 251.2 + 384[/tex]
[tex]v = 635.2 \: {cm}^{3} [/tex]
