Area Formulas that you should already know:
Rectangular Prisms:
Rectangle = L x W
Surface Area = 2(L x W) + 2(L x H) + 2(W x H)
Triangle = (1/2)bh
Volume = L x W x H
Trapezoid = [(B1+B2)/2] x h
Circle = (pi)r2
H
Circumference = 2(pi)r
L
W
Triangular Prisms:
Cylinders:
Volume: (1/2)(L x W x H)
Surface Area = 2(pi)r2 + 2(pi)rh
Volume = (pi)r2h
