512 is equal to 2^9. OK, I’ve memorised powers of 2 so I didn’t have to work that out.
The volume of a cube is equal to the length of it’s side cubed. Conversely, the length of the side of a cube of a given volume is the cube root of that volume.
In this case, it’s the cube root of (2^9) = 2^(9/3) = 2^3 = 8cm

Answer: 8cm
Step-by-step explanation: volume of the cube=a×a×a or a³ where a is the side or edge of the cube
given volume =512
applying the formula
512=a³
a=∛512
a=8cm
