Chapter 7 7.1** The surface are if an object is the total area of all exposed surfaces of the object, the volume of a solid object is the number of nonoverlapping unit cubes that will exacty fill the interior of the figure. The surface area S, and volume V, of a right rectangular prism with length L, width W, and height H, are S=2lw+2wh+2lh and V=lwh The surface of area S, and volume V, of a cube with side s are S=6s2 nd V=s3
 * Surface area and volume**

Surface area and volume of prism** The surface area of a prism may be broken down into 2 parts: the area of the bases, or base area, and the area of the lateral faces, or lateral area. The surface area S, of a right prism with lateral area L, base area B, perimeter p, and height h is S=L+2b or S+hp+2b The volume V, of a prism with height h and base area B is V=Bh The volume of a right rectangular prism with lenght L, width W, and height H, is given by V=lwh.Because the base area,B, of this type of prism is equal to LW, you can also write the formula for the volume as V= Bh.

 * Volume of right prisms**

Surface area and volume of pyramids** A pyraimd is a polyhedron consisting on a base, which is a polygon, and three or more lateral faces, The surface area S, of a regular pyramid with lateral area L, base p, and slant height L, is S=L+b or S=1/2 lp+b The surface area is the sum of the lateral areas ad the base area. The volume of a pyramid V, with height h and base b is v = 1/3 Bh. The altitude of a pyramid is the perpendicular segment from the vertex to the plane of the base, The height of a pyramid is the lenght of its altitude. A regular pyramid is a pyramid whose base is a regular polygon and whose lateral faces are congruent isosceles triangles.

Surface area and volume of cylinders** A cylinder is a solid that consists of a circular region and its translated image on a parallel plane, with lateralsurface connecting the cirlcles.The surface of a right cylinder with a radius of r and a height of h can be found by using a net. Surface are S, of a right cylinder with lateral area L, base area B, radius r, and height h is S=L+2b The volume of a cylinder V, with a radius r, height h, and bae B is V=Bh
