2) 12 inches
3) 24 inches
4) 36 inches

Answer 1

The thickness of a 1.5 ft thick concrete wall is 18 inches when converted from feet to inches.

Step-by-step explanation:

The question asks for the conversion of a wall thickness from feet to inches. To convert from feet to inches, you multiply by the number of inches in a foot, which is 12 inches.

1.5 feet × 12 inches/foot = 18 inches. Therefore, the thickness of the concrete in inches is 18 inches.
