8.5 m
clear my selection

Explanation:

Step1: Calculate total cm of wire

Each student uses 85 cm, 10 students: \( 85 \times 10 = 850 \) cm.

Step2: Convert cm to meters

Since \( 1 \, \text{m} = 100 \, \text{cm} \), divide by 100: \( \frac{850}{100} = 8.5 \, \text{m} \).

Answer:

8.5 m (the last option)
