Final answer:
Both Raul's upstairs hallway, measuring 8 feet, and his brother's downstairs hallway, measuring 96 inches, are the same length when converted to the same unit. They both measure 96 inches long.
Step-by-step explanation:
To find out which hallway is longer, we must compare the measurements of both hallways in the same units. First, we know that 1 foot equals 12 inches. Therefore, 8 feet is 8 × 12 = 96 inches.
Raul's upstairs hallway measures 8 feet, which we have converted to 96 inches. His brother measured the downstairs hallway at 96 inches. Hence, both hallways are the same length.
