Prism Volume

V = B·H

Prism SA

SA = Ph+(2B)

Pyramid Volume

V = (1/3)Bh

Pyramid SA

SA = (1/2)Pl+B (l = slant height)

Cylinder Volume

V = πr²h

Cylinder SA

SA = 2πrh+2πr²

Full Sphere Volume

V = (4/3)πr³

Semi Sphere Volume

V = (2/3)πr³

Full Sphere SA

SA = 4πr²

Semi Sphere SA

SA = 2πr² + πr²

Cone Volume

V = (1/3)πr²h

Cone SA

SA = πrl + πr² (l = slant height)

Frustum SA

SA = πrl - πrl + πr² + πr² (b-s+B+B) (l = slant height)
