Question 955534
a=edge of cube; A=surface area of cube
Each face of a cube has {{{area=a^2}}} and there are 6 faces,
so total surface area={{{6a^2}}}
{{{A=6a^2}}} Divide each side by 6.
{{{A/6=a^2}}} Find square root of each side.
{{{sqrt(A/6)=a}}}
{{{sqrt(96cm^2/6)=a}}}
{{{sqrt(16cm^2)=a}}}
{{{4cm=a}}} ANSWER: The edge of the cube (a) is 4 centimeters.
