Symbol • H: Height • L: Length • W: Width • UB: Upper base • LB: Lower base • P: Parameter • A: Area • V: Volume
Triangle • P = L1 + L2 + L3 • A = (LxH)/2
Square • P = 4L • A = LxL = L^2
Rectangle • P = 2(W+H) • A = WxH
Parallelogram • P = 2(L1 + L2) • A = WxH
Trapezoidal • P = UB+LB+L1+L2 • A = (UB+LB)xH/2
Circle • P = 2 x PI x r • A = PI x r^2
Prisms • A = 2 x BA + side area • V = BA x H
Cones • S = BA +side area • V = 1/3 x prisms
Spheres • S = 4 PI r^2 • V = 4/3 PI r^3
Sphere • R = 5 • R = 7
