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

Read Solution (Total 1)

10*3*3=90 cuboid,
to make a perfect cuboid it size should be of 10*10*10=1000
so extra cubes=1000-90=910
