Depends on shape
VOLUME
cube = a 3 
rectangular prism = a b c 
irregular prism = b h 
cylinder = b h = pi r 2 h 
pyramid = (1/3) b h 
cone = (1/3) b h = 1/3 pi r 2 h 
sphere = (4/3) pi r 3 
ellipsoid = (4/3) pi r1 r2 r3 
AND SURFACE AREA
Surface Area of a Cube = 6 a 2
(a is the length of the side of each edge of the cube)
In words, the surface area of a cube is the area of the six squares that cover it. The area of one of them is a*a, or a 2 . Since these are all the same, you can multiply one of them by six, so the surface area of a cube is 6 times one of the sides squared.
Surface Area of a Rectangular Prism = 2ab + 2bc + 2ac
Surface Area of Any Prism
(b is the shape of the ends)
Surface Area = Lateral area + Area of two ends
(Lateral area) = (perimeter of shape b) * L
Surface Area = (perimeter of shape b) * L+ 2*(Area of shape b)
Surface Area of a Sphere = 4 pi r 2
Surface Area of a Cylinder = 2 pi r 2 + 2 pi r h
