Answer: 25.2 Joules

Explanation:

Work = total heat energy = Fs = (24)(1.8) = 43.2 J

Heat = cube + floor = 43.2J

floor = 43.2 J - 18 J = 25.2 J

If the vertical component is 29.6 m/s down, and the horizontal component
is 54.8 m/s parallel to the surface, then the magnitude of the slanty vector is

   √(29.6² + 54.8²) = √(876.16 + 3003.04) = √3879.2  =  62.28 m/s .

That's 139 mph !  Wow !
