A block of metal has a width of 3.2 cm, a length of 17.1 cm, and height of 5.8cm . Its mass is 1.4kg . Calculate the density of the metal.

Question

anonymous · Answer

density is mass over volume

anonymous · Answer

mass/volume right?

anonymous · Answer

yes

anonymous · Answer

ok you already know the mass which is given as 1.4kg

so it's

1.4kg/volume

now you need to find volume.

anonymous · Answer

in this case the volume is length x  width x height

anonymous · Answer

can you tell me the volume?

anonymous · Answer

right and i got 317.376

anonymous · Answer

the kg needs to be in grams which im not good at converting

anonymous · Answer

1.4kg 

kilo=k=1000

anonymous · Answer

replace k with 1000 and multiply that number with 1.4

anonymous · Answer

dont forget the units for volume in this case are cm^3

anonymous · Answer

I think that's it. anymore questions?

Thanks!! And just one more .. A particular brand of gasoline has a density of 0.737 g/mL at 25 ∘C. How many grams of this gasoline would fill a 13.7gal tank?

anonymous · Answer

sorry i dont know that one. Im bad with conversions.
