Does an aluminum part have voids if its mass is 3 kg and its volume is 2 dm3? If so, find the volume of the void.

First, let’s calculate the volume of 3 kg of aluminum:
V = m / p = 3000 (gram) / 2.7 (g / cm) ^ 3 = 1111cm ^ 3
2dm ^ 3 = 2000 cm ^ 3
That is, the volume of the void = 2000-1111 = 889cm ^ 3 = 0.000889 m ^ 3
