Density of the concrete

Find the density of the concrete of the cuboid-shaped column has dimensions of 20 x 20 cm x 2 m if the weight of the column is 200 kg.

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=225=0.08 m3  h=m/V=200/0.08=2500 kg/m3
