Question

A wall has a height of 4m 25cm. if each brick is 5cm high, how many bricks were used to attain the given height of the wall? ​

Answer 1

• As per the data given in the question, we have to find the number of bricks to attain the given height.

       Given data:-

        1. Height of wall$=4m25cm.$

        2. Brick's height$=5cm.$

       To find- Number of bricks is used.

Step 1- We will know $1m=100cm.$ so we convert $metre$ into $centimetre.$

           We will get it,

           $4m=4\times100.$

           $=400cm.$

           Wall's height $= 400+25$

           $=425cm.$

• For finding the numbers of bricks used to attain the given height, We              will divide the wall's height by brick's height. we will get it,

          $=\frac{425}{5}=85.$

        Hence the total number of bricks used is $85.$

           

             

Answer 2

Given: The wall height is $4m. 25cm.$

The height of brick is $5cm.$

To find: how many bricks were used to attain the given height of the wall.

We know that $1m.=100cm.$

So, $4m$.will become after converting the meter into centimeter. i.e

$4m.=400cm.$

Now the height of the wall will be

$400cm.+25cm.\\=>425cm.$

To find the number of bricks used to attain the wall,

we will divide the wall height by bricks height.

i.e;

$=>\frac{425}{5} \\=>85$

Hence, the total number of bricks used to attain the wall is $85.$
