When finding the volume of a prism, the first step is to find the area of the cross-section. In this case, we have a circle of diameter 7m. The area of a circle is pi(d/2)2

Plugging in d=7 gives us 38.484510006474967171167381445174

To find the volume, you multiply the cross-sectional area by the height:

12 x 38.484510006474967171167381445174 = 461.81412007769960605400857734209

And so the volume is 461.8m3
