The aluminum and copper parts have the same volume. The density of aluminum is 2700 kg / cubic. Meters, copper density 8900 kg / m3. Find the mass of aluminum if it is known that the masses of the parts differ by 60g.
We use the mass formula m = p * V
m (1) / p (1) = m (2) / p (2)
x + 0.06 / 8900 = x / 2700
27x + 1.62 = 89x then
1.62 = 62x
X = 38.3 kg
Answer 38.3 and 38.36
