How do you measure volume and mass?
How? Volume with a pipet, graduated cylinder, or by weighing.
Mass is measured with a balance.
I don't think these answers are what you are looking for and if they are not please be a little more specific about what you are asking.
are you asking for their formulas?
Be careful with your answers as there is a difference between determining mass or volume and measuring them.
For example you can measure volume with say a graduated cylinder, but if you use the mass of the material (by weighing) then you are DETERMINING the volume as you need to do a calculation using the density.
The two are also quite different as volume is a derived unit (metres x metres x metres) whereas mass is a base (or fundamental) unit.

To measure volume, you typically use different methods depending on the object's shape. Here are a few common ways:
1. For regular-shaped objects (like a cube), you can measure the length, width, and height using a ruler, and then multiply these measurements together.
- For example, if you have a cube that is 2 centimeters long, 2 centimeters wide, and 2 centimeters tall, the volume would be 2 cm x 2 cm x 2 cm = 8 cm³.
2. For irregular-shaped objects, you can use a graduated cylinder and the displacement method.
- Fill the graduated cylinder partially with water, note the initial water level.
- Carefully lower the object into the cylinder, making sure it does not touch the sides or bottom.
- Measure the new water level. The difference between the initial and final levels represents the volume of the object.
- For example, if the water level rose from 50 mL to 75 mL after inserting the object, the volume of the object would be 75 mL - 50 mL = 25 mL.
To measure mass, you need a scale or balance:
1. For small objects, a digital kitchen scale or a jewelry scale can be used. Place the object on the scale and note the displayed mass.
2. For larger objects, a platform scale or a bathroom scale can be utilized. Place the object on the scale and record the mass.
It's worth noting that different units of measurements can be used for volume and mass, such as cubic centimeters (cm³) or milliliters (mL) for volume, and grams (g) or kilograms (kg) for mass. Make sure to use consistent units in your measurements for accurate results.
