If the surface area of a cube is 726 sq.cm., then its volume. in cubic centimeters, is
Solution
given,
surface area of cube$$=6\times a^2$$
according to the given condition,
$$6\times a^2$$=726
$$a^2$$=$$\frac{726}{6}$$
a=11
hence,volume of cube will be=$$a^3$$
=$$11^3$$
=1331 cubic cm
Therefore the volume of the cube is 1331 cubic cm
