Question

a cube 'a' has side thrice as long as cube 'b' . what is the ratio of the volume of cube 'a' to that of cube 'b '

Answer 1

Let the side of cube 'a' = 3x
Volume = (3x)^3 = 27x^3
Side of cube 'b' = x
Volume of cube b = x^3
Ratio = (27x^3)/x^3
= 27/1
So ratio of volume of cube a: cube b
= 27:1

Answer 2

Answer:

27:1

Step-by-step explanation:

let the side of A cube be 3x

then , volume = s³ = 3x³ = 27x³

side of cube B = x

Volume of cube B = s³ = x³

Ratio = 27x³/x³ = 27/1

27:1
