Answer:

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
