Question 130
If the ratio of volume of two cubes is 11 : 13, then what is the ratio of the sides of the two cubes ?
Solution
Let side of the two cubes be $$a$$ and $$b$$ units respectively
Ratio of volumes = $$\frac{a^3}{b^3}=\frac{11}{13}$$
=> $$\frac{a}{b}=(\sqrt[3]{\frac{11}{13}})$$
=> $$\frac{a}{b}=(11)^{\frac{1}{3}}:(13)^{\frac{1}{3}}$$
=> Ans - (D)
