Question

a pillar is made up of 3000 bricks.If the height of each is 10cm then find the height of the pillear (in meter)

Answer 1

Answer:

Height Of 1 Brick=10 cm

Pillar Is Made of 2000 Bricks

2000 bricks Have Total Height of=(2000×10)cm

=20000 cm

Height of 2000 Bricks=Height of Pillar

Height of Pillar=20000 cm

Or In metre

1 m=100 cm

20000cm=20000/100

=200 m

Height of Pillar=20000 cm

OR

Height of Pillar=200 m

Step-by-step explanation:

Answer 2

Answer:

Concept:

A centimetre (international spelling) or centimeter (American spelling) (SI symbol cm) is a unit of length in the metric system, equal to one hundredth of a meter, or one centimeter.

Divide the length value by 100 to convert from cm to m.

$m =\frac{cm}{100}$

$1 cm = 0.01 m$

$1 m = 100 cm$

Given:

• A pillar is made up of $3000$ bricks.
• The height of brick is $10cm$.

To Find:

We need to find the height of the pillar (in meter).

Solution:

The height of one brick is $10cm$ and pillar is made up of $3000$ bricks.

Let $H$ be the height of the pillar.

Height of the pillar $(H)$ is equal to the product of number of bricks $(N)$ in the pillar and height of the each brick $(B)$.

$H=N*B$

$H= 3000* 10$

$H=30,000 cm$

The height of the pillar is $30,000 cm$.

Lets convert centimeter into meter.

$1 m = 100cm$

$m =\frac{cm}{100}$

$30,000cm =\frac{30,000}{100}m$

$30,000cm= 300m$

Therefore, The height of the pillar is $300 m$.
