Answer:
729cm³
Step-by-step explanation:
surface area = 6a²
from the question
6a²=486
a²=486/6
a²=81
a=√81=9cm
volume of a cube = a³=9³=729cm³
I hope my answer helps you ☺☺

Answer:
We know that surface area of cube is 61².
It is given that the surface area of cube is 486cm², therefore
486 = 61²
→ l² = 486
6
→ l² = 81
→ l = √81
→ l = 9
Now, the volume of the cube is l³
therefore, the volume with length l = 9 is
V = 9³ = 729
the volume of the cube is 729cm³
