Question

A rectangular box measures internally 1.6m long, 1m broad and 60cm deep. The number of cubical box each of edge 20cm that can be packed inside the box is:
A) 30
B) 60
C) 90
D) 120

Answer 1

Hey.


Here is the Answer .


Volume of cuboid = L B H

Here Given :

L = 1.6 m

B = 1 m

H = 60 cm = 0.6 m


So, volume of the box = 1.6 × 1 × 0.6 m^3


Also, volume of a cube = edge^3

Here edge = 20 cm = 0.2 m

So, volume of cubical box = 0.2^3 m^3


So, no. of box

= (Volume of cuboid) / (Volume of cube)

= (1.6 × 1 × 0.6) / (0.2 × 0.2 × 0.2)

= 120


So, The number of cubical box each of edge 20cm that can be packed inside the box is 120.
