s = d /3^{1/2}
s = (A /6 )^{1/2}
s = V^{1/3}
d = s *3^{1/2}
d = (A /2)^{1/2}
d = V^{1/3}*3^{1/2}
SA
A = s^{2}*6
A = d^{2}*2
A = (V^{2} )^{1/3}*6
V = s^{3}
V = (d^{3} *3^{1/2} )/9
V = (A^{3}/216)^{1/2}
r= s / 2
Variables
S = Length of side. D = Length of diagonal. SA = Surface area. V = Volume. r = Radius of sphere to fit inside cube. R = Radius of sphere to pass through all vertices of cube.
