1. What is the volume of a cube with edge lengths of 2/ 3 units?

2. What is the edge length of a cube with volume27 /64 cubic units?

3. what is the side length of a square with area 1/ 16 square units?

Below in bold.

Step-by-step explanation:

The volume of a cube = x^3 where x is the length of each edge.

1.  Volume = (2/3)^3  = 2^3 / 3^3 = 8/27 unit^3.

2.  Edge length x = ∛(27/64) = 3/4 units.

3.  Side length of the square = = √(1/16) = 1/4 units.
