The surface area of our dodecahedron is 74324 square inches. Pr 2 x h or pi times the radius squared times height. Seeing how a cylinder is similar to a rectangular solid may make it easier to understand the formula for the volume of a cylinder.
The surface area of our dodecahedron is 74324 square inches.
The formula depends on the type of the solid. To understand the formula for the surface area of a cylinder think of a can of vegetables.
