Leena cut small cubes of 10 cm dimension each. She joined it to make a cuboid of length 100 cm, width 50 cm and depth 50 cm. How many more cubes does she need to make a perfect cube?
a) 500
b) 250
c) 750
d) 650

• {(100*100*100)-(100*50*50)}/(10*10*10)=750000/1000=750

• (10*50*50)/100=250-> these are the cubes presently having
  
  to make it perfect we need to have the dimensions 100cm,100cm,100cm (ie the double of the previous one) so the ans is 250.
