A large emerald with a mass of 982.7 grams was recently discovered in a mine. If the density of the emerald is 5.42 grams/cm2 , what is the volume? Round to the nearest hundredth when necessary and only enter numerical values, which can include a decimal point.

wolf1728 · Answer

the density should be 5.42 grams/cm3 shouldn't it?

wolf1728 · Answer

982.7 * 5.42 gms / cm3 =
5,326.23 cm3

nirmalnema · Answer

density= mass/volume
5.42=982.7/volume
volume=982.7/5.42
181.30 cm^3 because it is volume

anonymous · Answer

is that to the nearest hundredth?
