Question

calculate the edge of cube if its volume is 1331 cm3

Answer 1

Hi,

Let the edge of the cube = a cm

We know that
______________________________

volume of the cube ( V )= a^3 --------( 1 )
_______________________________

But , according to the problem given ,

V = 1331 cm^3 --------- ( 2 )

( 1 ) = ( 2 )

a^3 = 1331 cm^3

a^3 = ( 11 cm ) ^3

Therefore ,

a = 11 cm

Required edge of the cube = a = 11 cm

I hope this helps you.
