• Find the density of a block with a length of 8.0 cm, width of 4.0 cm, a height of 2.0 cm, and a mass of 32 g. Would the block sink or float in water? The density of water is 1.0 g/cm3. • What is the mass of an object with a density of ### #### that displaces ### ## of water? • Given the density of iron is 11.35 g/cm3, what would be the volume of a 1.1 g piece of iron? • Convert 725 Hm into meters. • Convert 2,330,000 ms into years.

find the volume of the block using the parametres you were given then density = mass/volume. compare the density of the block and that of the water and see for yourself.

"Given the density of iron is 11.35 g/cm3, what would be the volume of a 1.1 g piece of iron?" use ################ # = m/v that i gave you to find it, its easy just do the math the rest are just math

(things are mispelled or typed out diff because filter is dumb) Convert 2,330,000 ms into years. millisecond is 1/1000 of one se ond, so divide 2,330,000 by 1000 you have 2330 se onds now divide it by 60 to get minutes you have 38.83... mi utes divide by 60 to get hours .six four seven two of an hour divide by 24 to get days .026967.... d ys divide by 365 to get years .zero zero zero zero7388381.. years or 7.388381e-5
