Answer:

40.5 grams

Explanation:

mass = density × volume

Density is the same

Mass and volume vary propotionallly

12/Mass = (1/1.5)³

Mass = 12 × 1.5³ = 40.5 grams

Answer:

I think it is 40.5

Explanation:

If each 1cm cube is 12 grams, I figure the other cubes would be proportional and a 1.5cm cube comes up to be 3.375cm^3, not 1 cm^3, thus we multiply the rate to 3.375 to get 40.5 as the mass of the 1.5 cm cube
