Mathematics

1332.8 ft^3

Step-by-step explanation:

separate the two figures into a flat cylinder and a flat box

Volume of a cylinder= $\pi r^{2} h$

where radius= 3ft and height= 3ft

therefore

$=\pi (3)^{2} (3) \\= 84.8 ft^{3}$

now for the flat box:

volume of box= w*l*h

where width= 6ft, length= 16ft, height= 13ft

therefore

$=(6)(16)(13)\\=1248 ft^{3}$

now add the volume of the cylinder and box together

$84.8 + 1248\\= 1332.8 ft^{3}$
