thats were i got 2.

Answer 20

and what would be the right way to write it.

Answer 21

The dimensions of #6 are g/cm^3

Answer 22

also, wouldnt number six be worked out like this?
2x2x5=20/100

Answer 23

Density = Mass / Volume

D = 100 g / (2cm * 2cm * 5cm)

D = 100 g/20cm ^3

D = 5 g/cm^3

Answer 24

oh.

Answer 25

Answer 26

7. Mr. Smith’s students are making a raft from wood that will float. Jane wrote the following data in her journal:
Dimensions of raft : 1 m by 2m by 5m.
Mass of raft: 5 kg.
What is the density of the raft?

D = 5 kg/(1m * 2m * 5m)

D = 5 kg/10m^3

D = 1kg/2m^3

Answer 27

.5?

Answer 28

Yes, 1/2 = .5

Just leave the units kg/m^3

Answer 29

so answer= .5 kg m^3?
