A cube made out of lead has mass 12 grams. A side of the cube has length 1 cm. What would be the mass of a lead cube whose sides
lana66690 [7]

Answer:

I think it is 40.5

Step-by-step 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
