The number of bricks is 50000.
Step-by-step explanation:
Given : Bricks of size 20cm × 12cm × 5cm required to build a wall of volume 60 m³.
To find : The number of bricks ?
Solution :
The dimension of brick is 20cm × 12cm × 5cm.
The volume of the brick is V=l\times b\times hV=l×b×h
V=20\times 12\times 5V=20×12×5
V=1200\ cm^3V=1200 cm
3
Converting into m³,
1\ cm^3= 10^{-6}\ m^31 cm

=10
−6

1200\ cm^3= 1200\times 10^{-6}\ m^31200 cm

1200\ cm^3=0.0012\ m^31200 cm

=0.0012 m

The volume of the brick is 0.0012 m³.
The volume of the wall is 60 m³.
The number of bricks is given by,
n=\frac{\text{Volume of wall}}{\text{Volume of brick}}n=
Volume of brick
Volume of wall
n=\frac{60}{0.0012}n=
0.0012
60
n=50000n=50000
Therefore, the number of bricks is 50000.
