square = a^{ 2}

rectangle = ab

parallelogram = bh

trapezoid = h/2 (b_{1} + b_{2})

circle = *pi* r^{ 2}

ellipse = *pi* r_{1} r_{2}

triangle = (1/2) b h

equilateral triangle = [(3)/2]
a^{ 2} = (3/4) a^{ 2}

triangle given SAS = (1/2) a b sin C

triangle given a,b,c = [s(s-a)(s-b)(s-c)]
when s = (a+b+c)/2 **(Heron's formula)**

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* r_{1} r_{2} r_{3}

cube = 6 a^{ 2}

prism:

(lateral area) = perimeter(**b**) L

(total area) = perimeter(**b**) L
+ 2**b**

sphere = 4 *pi* r^{ 2}
