Weighed with a balance a block has 5 kg. Its volume is 10 cm3. What is his weight and density?
Solution:
We find the weight G:
G = m * g
G = 5 kg * 9.8
G = 49 N
We find the density (p):
p = m / V
p = 5 kg / 10 cm3
p = 0.5 kg / cm3
Legend
G = weight (N)
m = mass (Kg)
g = constant = 9.8 (N / kg)
p = density (reads) (kg / cm3)
V = Volume (cm3)
Solution:
We find the weight G:
G = m * g
G = 5 kg * 9.8
G = 49 N
We find the density (p):
p = m / V
p = 5 kg / 10 cm3
p = 0.5 kg / cm3

g = constant = 9.8 (N / kg)
p = density (reads) (kg / cm3)
V = Volume (cm3)
