The formula for volume is V = (L)(W)(H).  Length, width, and height are multiplied together.  In this case, height is thickness.  Since we are given the total area, length, and width, we just need to solve for the height/thickness.  Plug in the given values:

225 = (25)(18)(H)
225 = 450*H
H = 225 ÷ 450
H =  0.5

The concrete slab is 0.5 feet thick.
