Given:
Volume of the cube = 729 m^3
Find the cube's edge
Formula for the volume of the cube = l^3
Solution:
Solve for in terms of v. In order to do so take the cube root of both sides of the equation, to get the formula for l.
The cube root sign is the same as a^⅓
l = v ^⅓
l = (729)^⅓
l= 9 m
The length of the cube's edge is equal to 9 meters.
