Density 67774

The prism, whose base is square / the side of the square is 20 cm / 30 cm high, is made of oak wood, and weighs 8.5 kg. What is the density of oak wood?

Correct answer:

ρ =  708.3333 kg/m3

Step-by-step explanation:

m=8.5 kg a=20 cm m=20:100  m=0.2 m c=30 cm m=30:100  m=0.3 m  V=a a c=0.2 0.2 0.3=2503=0.012 m3  ρ=m/V=8.5/0.012=708.3333 kg/m3
