Question

A hollow cuboid is of dimensions 30cm * 27cm * 15cm. How many small cubes with side 3cm can be placed in the given cuboid?

  1. 340
  2. 450
  3. 220
  4. 564

The correct answer is: 450


    vol of cuboid=l*b*h=30*27*15
    vol of a cube = 3*3*3
    no. of cubes =vol of cuboid / vol of cube
    (30*27*15) /  (3*3*3)
    450
