Answer:
The surface area of a cube if all sides are 2/3 is 16
Explanation:
Use the equation SA = 6(a)^2 with a being the length of the side or edge. Substitute a for 2/3 and complete the equation.
SA = 6(2/3) = 4
SA = 4^2 = 16
So, in conclusion, the surface area of a cube if all sides are 2/3 is 16
