Platinum has a density of 21.45 G / CC. gold has a density of 19.3 G / CC.

a) which is larger 100 gram cube of platinum or a hundred grand cube of gold?

b) what is the length of each side of a 100 gram cube of platinum?

The answer to your question is:

a) The gold cube is larger.

b) lenght = 1.67 cm

Explanation:

Data

Platinum density 21.45 g/cm3 100 gram cube

Gold density 19.3 g/cm3 100 gram cube

Formula

density = mass / volume

a) Calculate volume

volume = mass / density

Platinum volume = 100 / 21.45 = 4.66 cm3

Gold volume = 100 / 19.3 = 5.18 cm3

b) Volume = lenght³

4.66 cm³ = lenght³

lenght = ∛4.66

lenght = 1.67 cm
