Question

How many small cuboids with dimensions 20 cm $\times$ 25 cm $\times$ 40 cm each can be accommodated in a cubical box of edge 2 m ?

• A. 4
• B. 4000
• C. 400
• D. 40

Answer 1

The correct option is C 400

Volume of one small cuboid = l $\times$ b $\times$ h
= 20cm $\times$ 25cm $\times$ 40cm
= 500 $\times$ 40
= 20,000 cu. cm

The edge of the cubical box = 2 m
= 200 cm
Now, Volume of the cubical box
= $200\times 200\times 200$
= 80,00,000 cu. cm

So the number of cuboids that can be just accommodated in the box = 80,00,000 $÷$ 20,000 = 400
