Question

The volume of a cube is 1331${cm}^3$. Find the length of the side of the cube.

• A. 22 cm
• B. 11 cm
• C. 121 cm
• D. None of These

Answer 1

The correct option is B

11 cm

Volume of a cube=$a^3$ (Where a is the side of the cube)

Thus, a= Cube root of volume= cube root of 1331

On Prime Factorizing 1331, we get

1331= 11 x 11 x 11= ${11}^3$

Thus, cube root of 1331=a=11 cm
