graduated cylinder and measures the new volume of water to be 32mL. what is the volume of
the rock?

Answer 1

The volume would be explanation times explanation because the explanation is the explanation

Step-by-step explanation:

Answer 2

`\boxed {\boxed {\sf v=12 \ mL}}`

Step-by-step explanation:

Grace found the volume of the rock using water displacement.

To calculate the volume, we must subtract the initial volume from the final volume.

`v_f-v_i`

The initial or original volume is 20 milliliters.

The final or new volume, after the rock is added to the water, is 32 milliliters.

`v_f=32 \ mL\\v_i=20\ mL`

Substitute the values into the formula and subtract.

`32 \ mL-20 \ mL`

`12 \ mL`

The volume of the rock is 12 milliliters.
