Any shape that has the same shape and area of cross-section all the way through is a prism. Therefore, a cylinder is a type of prism, as is a cuboid. Because all prisms are different in cross-section, each has a different equation for calculating their surface area. ... The Simple Cone's Surface Area...

Here's another example: suppose we want the surface area of the portion of the cone z2 = x2 + y2 between z = 0 and z = 4. The equation of the cone in cylindrical coordinates is just z = r, so we can take as our parameters r and t (representing q).

A typical problem involving the volume or surface area of a cone will give you information about one or more of the following quantities and ask you to calculate the others: volume, surface area, ... We will start with the equation for surface area since we were given the radius as 3 cm and the surface area as 24p.
