Question

A wall is 20 feet long and requires 1,470 bricks to build. How high is the wall?

Answer 1

Answer: The height of wall is 10.5 feet.

Explanation:

Since we have given that

Number of bricks to build = 1470

Length of wall = 20 feet

We need to find the height of wall.

As we know that

Bricklayer's formula is given by

`N=7LH\\\\1470=7* 20* H\\\\1470=140* H\\\\(1470)/(140)=H\\\\10.5\ ft=H`

Hence, the height of wall is 10.5 feet.
