What is the density of object A? Does it sink<br> or float in water?
Oksana_A [137]

Answer:

~1.5 g/cm3 and it does NOT float in water.

Explanation:

If you look at the graph, Object A weighs ~6 grams and is ~4 cm3 in volume

Density = Mass/Volume

Water has a density of 1 g/cm3 and because Object A density is higher than that of water, it sinks.
