3. how would you determine the density of an irregular object? (outcome # 3) (dok 3)
A. it would be impossible to determine the mass of the object without more
information.
B. d = m/v, so measure the mass of the object using a balance. then to find volume,
testbankseller.com measure
width, and length the height,
using an appro priate measuring tool.
