Question

A wooden cylinder beam of length 5 meters has a radius of 210cm. the wood density is 693kg/m

i) calculate the volume of the beam in cubic meters
ii) calculate the mass of the beam in kilograms.
​

Answer 1

Cylinder Volume = π • r² • height

Volume = PI * .210 m^2 * 5

Volume = 0.6927211801 cubic meters

Wood has a mass of 693 / cubic meter

mass = 0.6927211801 * 693 = 480.06 kilograms
