Question

A brick wall is 48.6 inches high and contains 17 rows of bricks. how tall is each brick if 8.65 inches is allowed for mortar?

1 .2.35
2.2.3
3.2.4

Answer 1

The height of each brick is approximately 2.35 inches, calculated by first finding the total height of the wall without mortar (48.6 - 8.65 inches) and then dividing it by the number of rows (39.95 inches / 17 rows).

Step-by-step explanation:

To find out how tall each brick is, we first subtract the total space taken up by mortar from the height of the wall. Then, we divide the remainder by the number of rows of bricks to find the height of a single brick.

1. Determine the total height of the wall without mortar: 48.6 inches - 8.65 inches = 39.95 inches.
2. Divide the height without mortar by the number of rows to get the height of each brick: 39.95 inches / 17 rows = 2.35 inches per brick.

Therefore, the height of each brick is approximately 2.35 inches.
