how many bricks of 20 CM length 10 cm breadth 4 cm height are required to make a cube whose each side is 2 metre?
Answers
Given:-
→Length of the brick=20cm
→Breadth of the brick=10cm
→Height of the brick=4cm
→Side of the cube=2m
To find:-
→Number of bricks required to make the cube whose each side is 2m.
Solution:-
Firstly,let's find the volume of the brick:-
=>Volume of the brick:-
=>Length×Breadth×Height
=>(20×10×4) cm³
=>800cm³
Thus,we got volume of 1 brick as 800cm³.
Now,let's find the volume of the cube.
We can see that the side of the
cube is given in m.
So,firstly let's convert the side of the cube from m to cm.
=>1m=100cm
=>2m=2(100)
=>200cm
Thus,side of the cube is 200cm.
=>Volume of the cube:-
=>(side)³
=>(200)³
=>8000000cm³
Hence,we got volume of the cube as 8000000cm³.
Now,number of bricks required:-
=>Volume of the cube/Volume of the brick
=>8000000/800
=>10000 bricks
Thus,the required number of bricks are 10000.

Hence,we got volume of the cube as 8000000cm³.
Now,number of bricks required:-
=>Volume of the cube/Volume of the brick
=>8000000/800
=>10000 bricks
Thus,the required number of bricks are 10000.
