Question

Bricklayers use the formula n=7lh to estimate the number n of bricks needed to build a wal of length L and height H, where L and H are in feet. Solve the formula for H. Estimate the height of a wall 28 ft. long that requires 1568 bricks.

Answer 1

well when you substitute the appropriate values you get

\[1568 = 7 \times 28 \times h\]

now solve for h

Answer 2
