Question

1. use the illustrations at right to answer these questions.

a. what is the volume of the liquid inside the container?
b. what is the volume of the rock in ml? in cm³?

Explanation:

Part a

Step1: Observe the first beaker

The first beaker (without the rock) shows the liquid level at 150 mL. So the volume of the liquid is the reading on this beaker.

Step1: Find the volume with the rock

The second beaker (with the rock) shows the liquid level at 200 mL.

Step2: Calculate the rock's volume (in mL)

Subtract the liquid volume (150 mL) from the volume with the rock (200 mL). So, \( 200 - 150 = 50 \) mL.

Step3: Convert mL to \( cm^3 \)

We know that \( 1\ mL = 1\ cm^3 \), so 50 mL is equal to 50 \( cm^3 \).

Answer:

The volume of the liquid inside the container is 150 mL.
