Answer 2

Answer:

$\huge{\boxed{\rm{\red{Answer=80,000}}}}$

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

=>n=80,000

Answer:-

Number of bricks are required=80,000
