Answer:
A
Explanation:
Well, the human skeletal system produce red blood cells into and for the body.
Density is calculated as mass divided by volume. We are given the mass of 15.0 grams, so we need to find the volume. For a cube, volume is calculated as (length of side)^3, so in this case, we have the length of a side as 44.5 mm, which is equivalent to 4.45 cm.
Volume = (4.45 cm)^3 = 88.1 cm^3
Then we divide mass by the volume:
Density = (15.0 grams) / (88.1 cm^3) = 0.170 g/cm^3
So the correct answer is A.
