Question

You have a piece of balsa wood that is 45 cm long, 8 cm high, and 4 cm wide. It weighs 50 g. What is its density?

Answer 1

`"Density"` `~=` `0.03*g*cm^-3`

Explanation:

`"Density, "rho` `=` `"Mass"/"Volume"`

`rho` `=` `(50*g)/(45*cmxx8*cmxx4*cm)` `=` `(50*g)/(1440*cm^3)`

`=` `??*g*cm^-3`.

So will balsa wood float? Why or why not?
