there is a cuboid of dimension 3cm*5cm*7cm. A total of 105 cuboidlet of volume 1 cm^3 are generated from it. Given that all the cuboidlets along the longest side(7 cm) is removed.Then find the difference between area of the bigger cuboid to the new cuboid.

• If the question says we have to remove cuboidlets along with side 7cm. i.e we will, after that, be left with a cuboid with volume 3x5x1 cm^3 i.e 15 cm^3.
  Now the total volume was 105 cm^3 and the new volume is 15 cm^3, the difference is 105-15=90 cm^3 and the ration is 1/7th of original cuboid.
