Find the length of diagonal (in cm) of a cube if the volume of the cube is 1331 cm3.
Answer & explanation
Correct answer: option 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
