Which statement is true about density.
Density is equal to the mass of an object.
Objects with a lesser density than water will sink.
Density is a physical property of matter.
Object with more density than water will float.
What is the formula used to find the volume of a solid object.
Volume = density x mass
Volume = length x width x height
Volume = mass x density x height
Volume = length + width + height
