Answer 2

The length of its side is 7.3 cm

Solution:

The volume of cube is given as:

$\text{volume of cube } = a^3$

Where, "a" is the length of side of cube

The volume of a cube is 385 cubic cm

Therefore,

$385 = a^3\\\\a^3 = 385\\\\a = \sqrt[3]{385} \\\\a = 7.274 \\\\ a \approx 7.3$

Thus length of its side is 7.3 cm
