Question

Bricklayers use the formula N = 7LH to estimate the number of bricks N needed to build a wall of height H and length L. What is the height of a wall that is 30 feet long and that requires 2,310 bricks to build? a. 12 ft c. 11 ft b. 10 ft d. 20 ft

Answer 1

Plug in 30ft for L and 2310 for n so you will get 2310=7(30)(h)... h would equal 11ft
