Find the length of diagonal (in cm) of a cube if the volume of the cube is 1331 cm3.

$331\sqrt{3}$ $21\sqrt{3}$ $11\sqrt{3}$ $111\sqrt{3}$

$11\sqrt{3}$

We know that, Volume of cube = (side)3 Length of diagonal = √3 side We have, Volume of cube = 1331 cm3 = (Side)3 = 1331 = Side = 11 cm Length of diagonal = √3 × side = 11√3 cm
