SA =Surface Area equals the total area of the surface of the solid. Measured in units squared 

V =Volume equals the number of cubic units that can fit inside the solid. Measured in units cubed 

LA =Lateral area which equals the surface area minus the bases

Surface Area Formula Chart

= apothem The distance from the center of a figure to the closest side

sl = slant height On a cone or pyramid it is the distance from the apex down the side to the edge of the base

B = Base Area the total area of the base and depends on the shape of the base.

h = height the vertical distance from the vertex of an object straight down to the base.

P = Perimeter of base the distance around the base
