This is one of a series of models illustrating the volume of solids designed by William Wallace Ross, a school superintendent and ... It is dissected into three pieces. A paper label attached to one ...

The formulae used to calculate the volume and surface area of cones and spheres will appear on the formula sheet provided with your M4 exam paper, ... {frustum} = 96 \pi – 24 \pi = 72 \pi\) ...

Conversely, if one or more of the frustum corners are in the bbox then, again, there is an intersection.<BR><BR>Things start to get a little hairy when neither of the previous two cases occur.

Notice the word solid in the question, meaning the frustum will have a top and a base as well as a curved surface. The top and the base are circles. \(\text{area of base} = \pi \times 8^{2} = 64 \pi\) ...
