How many small cuboids with dimensions 20 cm × 25 cm × 40 cm each can be just accommodated in a cubical box of 2 m edge?
None of the above
Volume of one small cuboids = l×b×h
= 20cm × 25cm × 40cm
Edge length of the cubical box = 2m = 200cm----(1m = 100cm)
Now, Volume of the cubical box
= 200cm × 200cm × 200cm
So the number of cuboids that can be just accommodated in the box
= Volume of the cubical boxvolume of the cuboid.
⇒ Number of cuboids = 200×200×20020×25×40=400
