A cube A has side thrice as long as that of cube B. What is the ratio of the volume of cube A to that of cube B?

Answer»

Given details are,

Let side of cube B be ‘x’ cm

Then, side of cube A = 3x cm

So now,

Ratio = volume of cube A / volume of cube B

= (3x)3 / (x)3

= 27x3/ x3 

= 27/1 

= 27:1
