      melting a cuboid with dimensions 90cm × 120cm × 150cm?
      A 1620 Correct Answer Incorrect Answer

      D 980 Correct Answer Incorrect Answer

      Solution

      Volume of cuboid = 90 x 120 x 150 ; Volume of cube = 10 x 10 x 10 , Hence number of cubes = volume of cuboid/volume of cube = (90 x 120 x 150)/(10 x 10 x 10) = 1620
