Leena cuts small cubes of 3 cubic cm each.She joined it to make a cuboid of length 10 cm,width 3cm, and depth 3 cm.How many more cubes does she need to make a perfect cube?
a)910 b)250 c)750 d)650

• Ans is a)910. To make cube we need 10*10*10=1000. now we have only 10*3*3=90.so the more cube we need are 1000-90=910.

• there is a mistake in question,instead of 1 cubic cm, they have given 3 cubic cm
  
  so if Leena cuts small cubes of 1 cubic cm each
  
  then : [(10*10*10)-(10*3*3)]/1 = 910
