A rectangular tank 10" by 8" by 4" is filled with water. If all of the water is to be transferred to cube-shaped tanks, each one 3 inches on a side, how many of these smaller tanks are needed?

• Volume of the rectangular tank=10*8*4=320 cubic inch
  Volume of the cube shaped tank=3*3*3=27 cubic inch
  Therefore, the No of smaller tanks required=320/27=11.85 or say 12 No. of cubic shaped tank required

• for rectangle : 10*8*4 = 320 units volume of water is filled
  for one cube : 3^3 = 27 units volume of water will be filled..
  
  27 * x = 320
  x = 320/27
  x = 11.851851852
  since we can't take 0.85 cube, we need take to one full cube so take the ceiling..
  so x = 12 cubes are required
