Question

12. If the sum of all edges of a cube is 36 cm, then find the volume (in cm) of that cube.​

Answer 1

Number of edges in a cube = 12

The sum of all edges of the cube = 36

The length of one edge = 36/12

                                        = 3

Volume of the cube,

=l x l x l

=3x3x3

=$27cm^{3}$

Answer 2

Sides of cube =6

Volume of cube =a^3

a= 36/6= 6
a= 6x6x6=216cm^3
