• ### Altitude of a Cylinder

The segment with one endpoint in the base of the cylinder, and the other endpoint in the plane that contains the other base, perpendicular to that plane.

• ### Altitude of a Prism

The segment with one endpoint in the base of the prism, and the other endpoint in the plane that contains the other base, perpendicular to that plane.

• ### Cubic Unit

A cube with edges of length one.

• ### Surface Area

The area of a surface--surface area is a two-dimensional unit of measurement.

• ### Volume

A measurement in three dimensions, it measures the combined length, width, and height of a solid.

• ### Formulae

 Surface Area of a Sphere A = 4Πr2

 Volume of a Circular Cone V = (1/3)Πr2h, where h is the length of the altitude

 Volume of a Circular Cylinder V = Πhr2, where h is the length of the altitude

 Volume of a Cone V = (1/3)Bh, where B is the area of the base and h is the length of the altitude

 Volume of a Cylinder V = Bh, where B is the area of the base and h is the length of the altitude

 Volume of a Prism V = Bh, where B is the area of the base and h is the length of the altitude

 Volume of a Pyramid V = (1/3)Bh, where B is the area of the base and h is the length of the altitude

 Volume of a Sphere V = (4/3)Πr3
