A piece of block that measures 4.0 cm by 5.0 cm by 3.0 cm has a mass of 180.0 grams. What is the density of the block?

d = 3 g/cm³

Explanation:

Given data:

Mass of block = 180.0 g

Dimensions = 4.0 cm× 5.0 cm× 3,.0 cm

Density of block = ?

Solution:

Volume of block = length × width × height

Volume of block = 4.0 cm× 5.0 cm× 3.0 cm

Volume of block = 60 cm³

Density of block:

d = m/v

d = 180.0 g/ 60 cm³

d = 3 g/cm³
