What is the formula for volume?
Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is length × width × height.
What is the measuring tool for volume?
Chemists use beakers, flasks, burets and pipets to measure the volume of liquids.
What is the most accurate tool to measure volume?
Volumetric flasks, burets and pipets are the most accurate with tolerances of less than 0.2%. To achieve these accuracies the person using the device needs to use the proper technique and the measurements need to made at the temperature for which the glassware was calibrated (usually 20 degrees C).
What is the most precise tool to measure volume?
Volumetric flasks are used to measure one volume with the highest degree of accuracy and are used to make standard solutions for analytical assays. For example, the calibration of a 100 mL volumetric flask can have an accuracy of +/- 0.1 mL.
What do you use to measure volume of a solid?
The volume of a solid is the measure of how much space an object takes up. It is measured by the number of unit cubes it takes to fill up the solid. Counting the unit cubes in the solid, we have 30 unit cubes, so the volume is: 2 units⋅3 units⋅5 units = 30 cubic units.
What are 3 ways to measure volume?
There are other units for measuring volume; cubic inches, cubic feet, cubic yards are all units used for measuring volume. Milliliters, liters, gallons are also used especially when measuring liquids. We write cubic sizes using a small 3 next to the unit.
What are 2 ways to measure volume?
Different Ways to Find Volume
- Solve for Volume by Space. All physical objects occupy space, and you can find the volume for some of them by measuring their physical dimensions.
- Solve for Volume by Density and Mass. Density is defined as an object’s mass per a given unit of volume.
- Solve for Volume by Displacement.
How do you determine the volume of an irregular solid?
You can find the volume of an irregular object by immersing it in water in a beaker or other container with volume markings, and by seeing how much the level goes up.
What is an irregular solid example?
Examples of irregular solids include rocks, prisms, beans and screws. Each of these objects feature an irregular shape that is not composed of other recognized shapes. An irregular solid is distinguished by the inability to determine its area, volume or mass by measuring its length, width and height.
Can we measure the volume of a regular solid using a measuring cylinder?
The volume of a solid object with a regular geometric shape (rectangular box, cube, cylinder, sphere) can be determined using the volume formula for the shape. For example, a good approximation of the volume of the battery shown below could be made using the formula for the volume of a cylinder.
What do you measure mass with?
Scientists measure mass with a balance, such as a triple beam balance or electronic balance. In science, the volume of a liquid might be measured with a graduated cylinder.
What units are used for measuring the density of liquids?
The mass of water is expressed in grams (g) or kilograms (kg), and the volume is measured in liters (L), cubic centimeters (cm3), or milliliters (mL). Density is calculated by the dividing the mass by the volume, so that density is measured as units of mass/volume, often g/mL.
What is the difference between density and volume?
Volume – How much space an object or substance takes up. Mass – Measurement of the amount of matter in an object or substance. Density – How much space an object or substance takes up (its volume) in relation to the amount of matter in that object or substance (its mass). The amount of mass per unit of volume.
How do you calculate mass and volume?
The Density Calculator uses the formula p=m/V, or density (p) is equal to mass (m) divided by volume (V). The calculator can use any two of the values to calculate the third. Density is defined as mass per unit volume.
How do you calculate the density of two liquids?
Suppose you have two masses M1(=M) and M2(=M) with volumes V1 and V2, respectively. Then the total density is the total mass divided by the total volume. So ρmix=2M/(V1+V2).
What is the formula for calculating density?
The formula for density is d = M/V, where d is density, M is mass, and V is volume.
How do you calculate the overall density?
The most accurate way to calculate the density of any solid, liquid or gas is to divide its mass in kilograms by its volume (length × width × height) in cubic metres. The unit for density is kg/m 3. The density of water is approximately 1000 kg/m 3 and the density of air is approximately 1.2 kg/m 3.
How do you find the density?
The formula for density is the mass of an object divided by its volume. In equation form, that’s d = m/v , where d is the density, m is the mass and v is the volume of the object.
What are the units of density?
Kilogram per cubic meter
How can I calculate average?
The average of a set of numbers is simply the sum of the numbers divided by the total number of values in the set. For example, suppose we want the average of 24 , 55 , 17 , 87 and 100 . Simply find the sum of the numbers: 24 + 55 + 17 + 87 + 100 = 283 and divide by 5 to get 56.6 .
What is my ideal weight in kg?
Ideal body weight (men) = 50 kg + 1.9 kg for every inch above 5 feet. Ideal body weight (women) = 49 kg + 1.7 kg for every inch above 5 feet.
What is my ideal weight for my age?

| 5ft 5″ (65″) | 114 to 144 lbs. | 150 to 174 lbs. |
How do you calculate weight and height?
Body Mass Index is a simple calculation using a person’s height and weight. The formula is BMI = kg/m2 where kg is a person’s weight in kilograms and m2 is their height in metres squared. A BMI of 25.0 or more is overweight, while the healthy range is 18.5 to 24.9.
