My brother has the following question on his 9th grade science homework. It's a teacher-typed page and not from the book. I can't figure it out. Any help would be greatly appreciated.
7. A barge has the dimensions of 25m by 10m and a height of 6m. What mass do the makers have to make it in order for it to float in fresh water?
volume=length times width times height.
the density of water is 1 g/cm^3. so.
therefore, the mass would have to be 1500.
I'm pretty sure that's right. It's been awhile.
