+
+To find the volume (centimeters cubed) of a cuboid you use the formula:
+
+`volume = Length * Width * Height`
+
+But someone forgot to use proper record keeping, so we only have the volume, and the length of a single side!
+
+It's up to you to find out whether the cuboid has equal sides (= is a cube).
+
+Return true if the cuboid could have equal sides, return false otherwise.
+
+Return false for invalid numbers too (e.g volume or side is less than or equal to 0).
+
+Note: side will be an integer
