Question

How many stones will it take to build the wall

Answer 1

The wall is 37' by 9'11". We know that there are 12 inches in a foot, so let's convert these measurements into inches:


`\sf 37\cdot 12=444~in`

`\sf 9\cdot 12=108+11=119~in`

Now let's find the area of the entire wall:


`\sf A=lw`


`\sf A=(444)(119)`


`\sf A=52836~in^2`

Now let's find the area of one brick:


`\sf A = lw`


`\sf A=(18.5)(8.5)`


`\sf A = 157.25~in^2`

Now divide this to the total area of the wall to find out how many bricks it will take to complete the wall:


`\sf 52836/ 157.25=\boxed{\sf 336}`

So it will take 336 stones to build the wall.
