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
def cube_checker(volume, side)
volume == side**3 && volume > 0
end
