Question

Bricklayers use the formula N= 7LH to estimate the number of bricks N needed to build a wall H give. In terms of the length and the number of bricks. b. What is the height of a wall that is 30 feet long and requires 2135 bricks to build?

Answer 1

The height of the wall is approximately 10.17 feet.

Explanation:

Given,

Length of wall = 30 feet

Total number of bricks = 2135

We have to find out the height of the wall.

To find out the height of wall, we have given the formula;

`N=7LH`

Where N stands for number of bricks, L stands for length of wall and H stands for height of wall.

So we substitute the given values, we get;

`2135=7*30* H\\\\2135=210H\\\\H=(2135)/(210)=10.166\approx10.17\ ft\\`

Hence the height of the wall is approximately 10.17 feet.
