The height of 3 courses of brick is determined by the standard size of a single brick. In general, a standard modular brick measures approximately 7.5 inches long, 3.5 inches wide, and 2.25 inches tall. When factoring in mortar joints that typically add about 0.5 inches between each course, the calculation for the height of 3 courses of brick would look like this:

- The height of one course of brick alone is about 2.25 inches.

- For three courses of brick, we multiply 2.25 inches by 3, which equals 6.75 inches.

- Additionally, there are typically 2 mortar joints in a stack of 3 courses, each adding about 0.5 inches, leading to 1 inch due to the two joints (0.5 inches x 2).

- Therefore, the total height is approximately 6.75 + 1 = 7.75 inches total.

Rounding this number typically results in 8 inches for practical applications, making 8 inches the accepted height when discussing courses of brickwork. This is why the answer is determined as 8 inches.
