Answer 3

The volume of the large rock is 140mL.

Explanation:
The initial volume of the graduated cylinder was 600mL. After adding the rock, the volume increased to 740mL. Therefore, the volume of the rock is the difference between the final volume (740mL) and the initial volume (600mL):

Volume of rock = final volume - initial volume
Volume of rock = 740mL - 600mL
Volume of rock = 140mL
