How do you do surface area and volume?

Depending on what shape or figure you are talking about, generally volume = Bh B = area of the base and for area greatly depend on what the object is.

square = side cubed

rectangle = L time H

triangle = base time height divided by 2

circle = pi time radius cubed

that should get you through what you need.

Prism; Surface area = Lateral Area + 2 (base)

Volume = Base times height

Cylinder; surface area = lateral area + 2 (base)

Volume = Base times height

Pyramid; Surface area = Lateral times base

Volume = 1/3 base times height

Cone; Surface area = Lateral area + base

Volume = 1/3 base times height
