Answer:
29 mL
Explanation:
Step 1: Given data
Volume of water inside the graduated cylinder: 35 mL
Volume of the water after placing the keys: 64 mL
Step 2: Calculate the volume of the keys
The rise in the level of the water is due to the volume of the keys. We can find the volume of the keys by subtracting the final volume to the initial volume.
V(keys) = 64 mL - 35 mL = 29 mL
