8. The volume of a closed space can be measured by determining the
   number of cubic units that can fit inside a given space without any gaps or
   overlaps.
   What is the length (in cm ) of each edge of a cube whose volume is
   numerically equal to the area of a square whose length of each side
   measures 8 cm ?
   A. 64

To find the volume of the cube that is equal to the area of the square, we first determine the area of the square. With each side measuring 8 cm, the area is calculated as 8 cm x 8 cm = 64 cm². The formula for the volume of a cube is V = s³, where s is the length of one edge. Setting s³ equal to the area (64 cm²), we solve s = 4 cm, so the length of each edge of the cube is 4 cm, not 64 cm as indicated in option A.

Now, the next time you encounter problems involving volumes and areas, remember to keep the formulas straight! Mixing them up can take you on a wild number chase. Cubes and squares may seem similar, but they have distinct properties that lead to different calculations.
