What is the formula for Density?

• mass x volume

• length x width x height

• volume / mass

• mass / volume

What is the density of water?

• 1.0g/ml

• 10.0g/ml

• .1g/ml

• 100.0g/ml

The object on the right FLOATS because its DENSITY is less than Water's density.

• TRUE

• FALSE

What could be a possible density of the FLOATING APPLE?

• 1.5g/cm3

• 10.0g/cm3

• 0.5g/cm3

• 25.5g/cm3

What could be a possible density of the fork that sinks?

• 0.5g/cm3

• 2.5g/cm3

• 0.01g/cm3

• 0.2g/cm3

What happens to the density if we CUT something in half?

• It goes up

• It goes down

• It stays the same

• It turns to zero

What is the formula for volume?

• length + width + height

• length x width x height

• mass / volume

• length = width x height

What is the definition of volume?

• amount of space something takes up

• how much matter something has

• how big something is

• how small something is

What is the volume of this rectangle?

• 16m3

• 24m3
