Answer:
Step-by-step explanation:
Given:-
10meters long ,5meters wide and 2 metres height has to be constructed by using the bricks of 25 cm×10cm×5cm.
To find:-
How many Number of bricks are required.
Solution:-
Length of the stage (l)=10m
width of the stage (b)=5m
Height of the stage (h)=2m
Volume of the stage
=Volume of a cuboid=lbh cubic.units
=10×5×2m³
=100 m³
We know that 1 m³=1000000cm³
100m³=10,00,00,000cm³
Volume of the stage =10,00,00,000cm³----(1)
measurements of the brick=25cm,10cm and 5cm
Volume of the brick
=Volume of the cuboid
=lbh cubic units
=25×10×5cm³
=1250 cm³
Volume of the brick=1250cm³-----(2)
Let the required bricks be 'n'
Volume of 'n' bricks=n×1250 cm³------(3)
Using Concept:-
For number of bricks required to construct the given stage ,then volume of the stage =Volume of n bricks.
Now,
(1)=(3)
=>10,00,00,000=n×1250
=>n=10,00,00,000/1250
