Answer 1

Answer:

HOPE IT HELPFUL

Step-by-step explanation:

This can be done by conservation of volume.

Volume of bigger cuboid = l×b×h

= 2.5 × 1.5 × 2 = 7.5

Volume of smaller cube = 0.5 × 0.5 × 0.5(50 cm = 0.5 m) = 0.125

Let the no. of small cubes = n

Total volume of small cubes = n × 0.125

Now 7.5 = n × 0.125 ( conservation of volume)

n = 60
