How do you find volume of Styrofoam?
Half of the diameter is called the radius. Then use the formula: Volume=(4/3)*pi*radius^3. the little ^3 means to multiply the radius times the radius times the radius (r*r*r). This won’t be exact because it only works for perfectly round balls and styrofoam balls tend to have bumps on them.
What is the weight per volume of Styrofoam?
Styrofoam weighs 0.05 gram per cubic centimeter or 50 kilogram per cubic meter, i.e. Assume the volume of the mass is negligible compared to that of the sphere.
How much does Styrofoam weigh in grams?
How much does a Styrofoam cup weigh? Expanded polystyrene weighs 0.05 grams per cubic centimeter or 50 kg per cubic meter, i.e. the density of expanded polystyrene is 50 kg / m³ at 20 ° C (68 ° F or 293.15 K) at normal atmospheric pressure.
What is the density of a Styrofoam ball?
Solved A spherical styrofoam ball (density=300 kg/m3) is | Chegg.com.
What is the volume of ice?
0.92 g = 1 mL – “per” is equivalent to an equal sign. The increase in volume of ice is about 9%….
| Comparison of: | |
|---|---|
| Liquid water | Ice |
| Volume = 100 mL | Volume =? mL |
| Density = 1.0 g/mL | Density = 0.92 g/mL |
How is foam weight calculated?
To calculate the density of a piece of foam, you divide the weight of the foam by its width x height x length. If you measure in feet, density is expressed in weight per cubic foot. Say the density of a mattress is four pounds per cubic foot.
How much does Styrofoam weight?
Typical polystyrene foam packaging and insulation is usually in the density range of 1 to 2 pounds per cubic foot. What this means is if you have a 12-inch x 12-inch x 12-inch cube of solid foam, it would weigh between 1 and 2 pounds.
How much does Styrofoam weigh?
How do you calculate foam weight?
As an example, consider a foam layer that weighs 100 pounds and measures 25 cubic feet in total. By dividing the total weight by the total number of cubic feet (100 divided by 25, in this case), we can see that this layer has a density of 4 pounds per cubic foot (4 PCF).
