Question

Two cubes are such that the length of the side of cube I is twice the length of the side of cube II. Find the ratio of the volume of cube I to that of cube II.​
Answer fast.... please

Answer 1

let the length of the side of cube 1 be 2x and the length of the side of cube 2 Be X.

volume volume of cube is equals to

${x}^{3} and \: {2x}^{3}$

then ratio between volume is

$2x \times 2x \times 2x \div x \times x \times x$

which is

$2 \times 2 \times 2$

which is 8

so the ratio is 1:8
