Cone from cube

From a wooden block, 20 cm high was the turned largest possible cone. Calculate its weight if you know that the density of wood was 850 kg/m3

Correct answer:

m =  1.7802 kg

Step-by-step explanation:

a=20 cm ρ=850 kg/m3  r=a/2=20/2=10 cm h=a=20 cm V=13 π r2 h=13 3.1416 102 202094.3951 cm3  V1=V m3=V/1000000  m3=2094.3951/1000000  m3=0.00209 m3  m=ρ V1=850 0.0021=1.7802 kg
