Mass and Volume are related through Density where: Volume x Density = Mass As for your question, styrofoam is a brand name that we use to describe any polystyrene foam. As such, its density varies depending on the manufacturer. From what I found in this answer: http://wiki.answers.com/Q/What_is_the_density_of_styrofoam it looks like you would have anywhere from 50 to 400 cm3 (50 to 400mL)
Your question isn't specific enough. Depending on the type of metal the mass will be different and the volume will change. Heavier metals will have less volume for those 10 grams, while a lighter metal would require more volume to achieve the same 10 grams.
Density= mass/volume 25/10 = 2.5 g/cm3
10 grams per c.c.
Styrofoam is a mass noun, it is already plural. It is most often encountered as an adjective - i.e. a Styrofoam mug, a Styrofoam container ... and these do not have a plural just as there is no plural for "big" in 10 big mugs or 20 big containers, we just say 10 Styrofoam mugs, 20 Styrofoam containers.
Greater in what way? They both have the same mass. Aluminium, being less dense will have a greater volume, but being more abundant will have a smaller value.
Not enough information. You would also have to know either the volume, or the density, of the object.
1 Volume of water is nothing but volume of water measured in liters or ml EG Volume = mass/density 1 Volume= 1 gm/1 gm/cc = 1 cc therefore 10 volume = 10 cc if it is in KG, 10 volume= 10 kg/10kg/L = 10 L
The equation for the volume of a cube is V=L3 where L is the length of the side (in your case 10). So, you can find the volume by taking 10*10*10.
6.0*10^12 gram
Volume: 8*10*12.5 = 1000 cubic cm
Depends on the density of the material (use gram / cubic centimetre) note: 10 mg = 0.01 gram as example, use water @ 1 g / cu. cm. > volume = mass / density > In this case volume = 0.01 / 1 > So volume = 0.01 cu. cm.
Answer is in the question 10 gram
