Answer:
Explanation:
The total mass of the alloy is the sum of the masses of the two metals:
mass = density x volume = (8800 kg/m³ x 15 m³) + 850 kg = 132,000 kg + 850 kg = 132,850 kg
The total volume of the alloy is the sum of the volumes of the two metals:
volume = 15 m³ + 6.2 m³ = 21.2 m³
Therefore, the density of the alloy is:
density = mass / volume = 132,850 kg / 21.2 m³ ≈ 6266 kg/m³
Rounding to the nearest integer, the density of the alloy is 6266 kg/m³.
