7.1 - Surface Area and Volume Formulas ( SA=Surface Area; V=Volume; h=height; w=width; l=length; s=side ) SA = 2lw + 2wh + 2lh V = lwh SA of Cube = 6s^2 V of Cube = s^3

Altitude - A segment that has endpoints in the planes containing the bases and that is perpendicular to both planes. Height - The length of an altitude. Cavalieri's Principle - If two solids have equal heights and the cross sections formed by every plane parallel to the bases of both solids have equal areas, then the two solids have equal volumes. Volume of a Prism - The volume of a prism with height //h// and base area //B// is V=//Bh//

Pyramid - a polyhedron consisting of a base, which is a polygon, and three or more lateral faces. The lateral faces are triangles that share a single vertex, called the vertex of the pyramid. Each lateral face has one edge in common with the base, called a base edge. The intersection of two lateral faces is a lateral edge. Altitude - The perpendicular segment from the vertex to the plane of the base. Height - Length of the Altitude. Regular Pyramid - A pyramid whose base is a regular polygon and whose lateral faces are congruent isosceles triangles. In a regular pyramid, all of the lateral edges are congruent, and the altitude intersects the base at the center. The length of an altitude of a lateral face of a regular pyramid is called the slant height of the pyramid. Surface Area of a Regular Pyramid - The surface area, S, of a regular pyramid with lateral area //L//, base area //B//, perimeter of the base //p//, and slant height //l// is S=L + B or 1/2lp + B Volume of a Pyramid - The volume, V, of a pyramid with height h and base area B is V = 1/3Bh

Cylinder - A solid that consists of a circular region and its translated image on a parallel plane, with lateral surface connecting the circles. Altitude - A segment that has endpoints in the planes containing the bases and is perpendicular to both planes. The height of a cylinder is the length of an altitude. Axis - The segment joining the centers of the two bases. Right
