Density of the concrete

If the weight of the cuboid-shaped column is 200 kg, find the density of the concrete with dimensions 20 x 20 cm x 2 m.

Correct answer:

h =  2500 kg/m3

Step-by-step explanation:

a=20 cm→ m=20:100  m=0.2 m b=20 cm→ m=20:100  m=0.2 m c=2 m  m=200 kg  V=a⋅ b⋅ c=0.2⋅ 0.2⋅ 2=252​=0.08 m3  h=m/V=200/0.08=2500 kg/m3
