A home has a relatively large rectangular tank and smaller cube-shaped tanks that can store water. The choices between above two types are made based on the needs of the day. Whenever, rectangular tank is to be cleaned, the water can be transferred into cube shaped tanks. On a certain day, the rectangular tank of dimensions 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 this cube shaped tanks are needed?

• i think it is nearly 12 becz volume of rectangular tank is 8*4*10=320 nd volume of small cube is 3^3=27 so 320/27=12.............

• It should be 12 such tanks are needed.
  
  Volume of rectangular shaped tank = 10*8*4=320
  volume of 1 cube shaped tank=3*3*3=27
  
  Number of cube shaped tank = 320/27=11 and 23 is remaining.
  so, for 23 one extra tank is required.
  Total tank=11+1=12.
