    Are you trying to find the buoyancy?

    the volume of water raised = final volume - initial volume like if u have this -|dw:1442242816214:dw| can u find out the change in volume?

    The lines on the cylinder are the volume. In the one on the left the volume is 25 mL before and 35 mL after. So the volume of the rock is 35 mL - 25 mL = 10 mL

    yes final volume= volume after the block is immersed in the test tube =30 initial volume=volume before the block was not immersed in the test tube=20 the reason of the volume hike is because of the block and the hike in volume = volume of the block hike in volume is= final - initial =30-20 =10 so in this case volume of rock is 10ml

    For the second pair of Graduated Cylinders, Without said object inside we are at 27.5 ml, after we get bumped to 37.5. Then like PeachPi said, 37.5-27.5=10 ml,
