Question 104

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
