Question

a wall 15m long 30cm wide and 4 m height in made of bricks each measuring 22 cm into 12.5 cm into 7.5 CM if one upon 12 of the total volume of the wall consist of portrait how many bricks are there in the wall​

Answer 1

Answer:

Step-by-step explanation:

The dimension of the wall are

Length =15m

Breadth =0.3m

Height =4m

We know that

Volume of the wall=1×b×h

By substituting the values  

Volume of the wall =15×0.3×4

So we get

Volume of the wall =18 cm  3

It is given that the wall consists of 1/2 mortar

So we get

Volume of one mortar =1/12×18

By division

Volume of mortar 1.5 m  3

So the volume of all = Volume of wall -Volume of mortar

By substituting the values

Volume of wall =18−1.5

By subtraction

Volume of vall =16.5 m  

Length =22cm=0.22 m

Breadth =12.5 cm=0.125 m

Height =7.5cm=0.075 m

We know that  

Volume of one brick =1×b×h

By substituting the values

Volume of one brick =0.22×0.125×0.075

So we get

Volume of one brick =0.0020625 m  3

So the number of bricks = Volume of bricks / Volume of one brick

By substituting the values

Number of bricks =  

0.0020625

16.5

So we get

N umber of bricks =8000

Therefore, the number of bricks in the wall are 8000.

Answer 2

Answer:

the number of bricks is 8000...
