Which of the following items would have the highest density?

A. A 2 cm3 block of lead with a mass of 11 grams

B. A 12 cm3 block of wood with a mass of 3 grams

C. A 12 cm3 block of aluminum with a mass of 2 grams

Answer:

Lead has the highest density when compared to wood and aluminum.

Explanation:

Density can be calculated by the given formula

Density = Mass : Volume

Density of Lead = 11gm : 2cc

= 5.5 gm/cc

Density of Wood = 3gm : 12cc

= 0.25 gm/cc

Density of aluminum = 2gm : 12cc

= 0.166 gm/cc

Hence, Lead has the highest density of 5.5 gm/cc.
