The lightest balsam wood mass of wood of this tree is 12 g with a volume of 100 cm3

The lightest balsam wood mass of wood of this tree is 12 g with a volume of 100 cm3, determine the density of the wood.

Given:
V = 100 cm ^ 3;
m = 12 g.
Find: p (g / m ^ 3); p (kg / m ^ 3)
Decision:
First, for convenience, it is necessary to transfer the variables given in the condition into a more convenient system of calculus. Then we get:
V = 0.0001 m ^ 3 and m = 0.012 kg.
In order to solve the problem, you need to use this formula: p = m / V.
We know the values of all the variables in this formula, so we just have to substitute them and calculate the answer.
p = 12/100 = 0.12 g / cm ^ 3
p = 0.012 / 0.0001 = 120 kg / m ^ 3.
Answer: 0.12 g / cm ^ 3 and 120 kg / m ^ 3.
