Morphology
The meaning is compositionally derived from 'cube' (the third power) and 'root' (a solution value): a cube root is the number which, when raised to the third power, gives the target number. This mathematical construction is literal and cross-linguistically common, so a B1 learner who knows both constituents should be able to infer the meaning.
Etymology
Cube root comes from the picture of a cube: a cube's volume is its side length multiplied by itself three times, so a cube with side 3 has volume 3 times 3 times 3, which equals 27, and the root is the side length that makes that volume. That's why 'cube root' means the 'number that you multiply by itself twice' to get the given number.
