Question

A piece of wood with a specific gravity of 0.5 has a volume of 200 cm3. What weight of copper with a specific gravity of 9 must be attached to the piece of wood to just submerge it in water? Please show your working

Answer 1

Converting a specific gravity into a density is as simple as multiply the SG by the reference density for which it was based. In most cases, this is the density of water, and therefore your multiply the SG by 1 to yield your density in g/cm^3.

I hope this ans helps you

Thank you!
