Density 2

What is the density of a piece of driftwood that has the mass of 25 grams and a volume is 30 cm to the 3rd power. And how do I figure it out?

Result

d =  0.833 g/cm3

Solution:

$m=25 \ \text{g} \ \\ V=30 \ \text{cm}^3 \ \\ d=m/V=25/30 \doteq \dfrac{ 5 }{ 6 } \doteq 0.8333 \doteq 0.833 \ \text{g/cm}^3$

Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
