Thank you!
2900 grams (1 cm^3/2.7 grams) = 1074 cm^3
Volume = Mass / Density
Given that the mass of the pile of aluminum cans is 2.9 kg and the density of aluminum is 2.70 g/cm³, we need to convert the mass from kg to grams to match the units of density.
1 kg = 1000 g
So, the mass of the pile of aluminum cans in grams is:
2.9 kg * 1000 g/kg = 2900 g
Now we can plug in the values into the equation:
Volume = 2900 g / 2.70 g/cm³
Calculating this gives us:
Volume = 1074.07 cm³ (rounded to two decimal places)
Therefore, the volume of the solid cube formed from the melted aluminum cans is approximately 1074 cm³. Therefore, the correct answer is option b. 1074 cm³.
