if the height of a chimney is 60 m and the height of 100 bricks is 3 m then find the no. of bricks used.
Answers
Answer:
Height of chimney = 60m
Height of 100 bricks = 3m
No. of bricks used = (60m ÷ 3m) × 100 bricks
=> 20m × 100 bricks
=> 2000 bricks
Step-by-step explanation:
I.e, 2000 bricks are needed
Concept
A product is the found by using multiplication, or an expression. It is usually expressed as under:
Product= Number 1 * Number 2
Given
Height of a chimney is 60 m,
Height of 100 bricks is 3m.
To find
Number of bricks used in the chimney.
Explanation
We have been given that the height of a chimney is 60m and the height of 100 bricks is 3m. We have to first find the height of 1 brick which can be calculated as:
Height of 1 brick= Height of 100 bricks/100
Height of 1 brick=3/100=0.03 m
Number of bricks used in the chimney can be calculated as under:
=height of chimney/height of 1 brick
=60/0.03
=6000/3
=2000 bricks.
Hence 2000 bricks are used in the chimney.
