(100points) In the lab in this lesson, what measurement below was closest to the density of the ball, AND expressed in an SI derived unit based on SI base units?
1.6 kg/m3
0.9 g/cm3
0.0015 kg/m3
1.3 g/cm3

Which conclusion, based on measurements of the ball in the lab in this lesson, is correct?
The density of the ball was closest to 1.5 g/cm3, so it was made of natural rubber.
The density of the ball was closest to 0.92 g/cm3, so it was made of gum rubber.
The density of the ball was closest to 1.5 g/cm3, so it was made of synthetic or manufactured rubber.
The density of the ball was closest to 1.23 g/cm3, so it was made of Neoprene rubber.

Which statement is consistent with the findings from the lab in this lesson?
The density of the ball was closest to 1.5 g/cm3, so it was made of a synthetic or manufactured rubber. Therefore, it could not be from the Maya civilization.
The density of the ball was closest to 0.45 g/cm3, so it was made of scrap rubber. Therefore, it could be from the Maya civilization.
The density of the ball was closest to 1.2 g/cm3, so it was made of a hard rubber. Therefore, it could not be from the Maya civilization.
The density of the ball was closest to 1.1 g/cm3, so it was made of soft commercial rubber. Therefore, it could not be from the Maya civilization.
