a wall is 100m long ,0.3 broad and 4.5m high .how many bricks of size 15cmlong 5cm width and 5cm thick are required to construct wall?​

no of brick=volume of wall/volume of brick=(10000×30×450)/((15×5×5)=135000000/375=360000.is your answer.

here

100m=10000cm

0.3m=30cm

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
