Surface area and volume of prisms


Finding the surface area of a right prism The surface area, SA, of a right prism with lateral area L, base B, perimeter p, and height h. SA=L+2B or SA=hp+2B

Finding the volume of a prism use this formula V=Bh base times height.

Surface area and volume of cylinders
**=3.14**

Surface area SA, or Volume V, of a right Cylinder with lateral area L, base area B, radius r, and height h

To find SA use this formula SA=L+2B or S= 2(pi)rh+2(pi)r^2

To find the volume us this formula V=Bh or V=(pi)r^2h

The bases of the cylinder are the flat surfaces of the top and bottom.
