The document discusses calculating volumes of geometric solids such as prisms, cylinders, pyramids, and cones. It provides formulas for calculating volumes of right and oblique prisms and cylinders as well as formulas for pyramids and cones. Examples are given of applying the volume formulas to various solids. The key points are that volumes of prisms and cylinders do not depend on whether they are right or oblique and the formulas for calculating volumes are V = Bh for prisms and cylinders, V = 1/3Bh for pyramids, and V = 1/3πr^2h for cones.
