length = 2.2 cm

height = 1.7 cm

width = 7.5 cm

**Question 2** (2 points)

What is the density of a 16.97-g object if the dimensions of the block are:

length = 12.6 mm

height = 6.8 cm

width = 0.014 m

**Question 3** (2 points)

What is the density of a 21.73-g irregularly shaped object if the initial volume of water was 23.4-mL and the volume rose to 56.0-mL after the object was added?
