Applying geometric concepts in modelling

What is the density of a plastic ball that has a volume of 6cm³ and a mass of 12g? 

• 2g/cm³
• .5g/cm_³
• 72g/cm³
• 4mL

What is the formula for volume?

• Volume = Mass - Density

• Volume = Mass + Density

• Volume = Mass x Density

• Volume = Mass / Density

Calculate the volume of a substance which has a mass of 53.5 cm³ and a density of 4.76 g/cm³.

• 11.24 g

• 254.66 g

• 0.09 g

• 35.5 g

What is the formula for density?

• density = mass x volume
• density = mass / volume
• density = mass + volume
• density = mass - volume

A piece of copper has a mass of 89g and a volume of 10 cm3.  What would be the density of the copper?

• 0.89 g/cm3
• 89 g/cm3
• 8.9 g/cm3
• 890 g/cm3

What is the volume of 150 grams of lead if it has a density of 11.3 g/cm³?

• 13.3 g
• 13.3 cm³
• .075 g
• 1695 cm³

A student has a brick of clay. It has a density of 11.75 and has a mass of 250.75 g. What is the volume of the block?

• 2946.31 cm³

• 21.34 cm³

• 0.05 cm³

• 3.7 cm³

Joey finds a treasure chest packed with metallic coins. The chest has a volume of 1.5 m³ .The coins have a total mass of 16,950 kg. Hoping to find gold, he calculates the density to determine the metal of the coins.

• Bronze (8700 Kg/m³)
• Silve (10,500 Kg/m³)
• Lead (11,300 Kg/m³)
• Gold (19,300 Kg/m³)
