A cube has a volume of 27 cubic units. What is the length of one of its edges?

To find the length of one edge of a cube when you know the volume, you can use the formula for the volume of a cube:

[ V = s^3 ]

where ( V ) is the volume and ( s ) is the length of one edge.

Given that the volume ( V = 27 ) cubic units, you can set up the equation:

[ s^3 = 27 ]

Next, take the cube root of both sides to solve for ( s ):

[ s = sqrt[3]{27} ]

Since ( 3^3 = 27 ), it follows that:

[ s = 3 ]

So, the length of one edge of the cube is 3 units.
