Formulas For Kansas Mathematics Assessment

Variables Key:

A = area l = length S.A. = surface area
b = base r = radius V = volume
B = area of the base s = side w = width
h = height

Volume Formulas:

Cylinder     V = pr2h  Sphere      V = pr3 

Pyramid      V = Bh 

 Cone         V = Bh  =  pr2h

Surface Area:

Rectangular Prism                          S.A. = 2lh + 2hw + 2wh
Cube                                             S.A. = 6s2
Sphere                                           S.A. = 4pr2
Square Pyramid                             S.A. = b2 + 2bh
Closed cylinder                              S.A. = 2pr2 + 2prh
Cylinder open on one end              S.A. = pr2 + 2prh
Cylinder open on both ends           S.A. = 2prh
Right circular cone                         S.A. =  pr+ pr2
