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

Answer:

The height of the wall is approximately 10.17 feet.

Step-by-step 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;

$2135=7\times30\times H\\\\2135=210H\\\\H=\frac{2135}{210}=10.166\approx10.17\ ft$

Hence the height of the wall is approximately 10.17 feet.
