FORMULA REFERENCE SHEET 
Shape  Formulas for Area (A) and Circumference (C) 
Triangle  A = bh = x base x height 
Rectangle  A = lw = length x width 
Trapezoid  A = (b_{1} + b_{2})h = x sum of bases x height 
Parallelogram  A = bh = base x height 
Circle 
Figure  Formulas for Volume (V) and Surface Area (SA) 
Rectangular Prism 
V = lwh = length x width x height SA = 2lw + 2hw + 2lh = 2(length x width) + 2(height x width) + 2(length x height) 
General Prisms  V = Bh = area of base x height SA = sum of the areas of the faces 
Right Circular Cylinder  V = Bh = area of base x height SA = 2B + Ch = (2 x area of base) + (circumference x height)
