Question:
A beam 9m long 50cm wide and 20cm deep is made of wood which weighs 30kg per m3,find the weight of the beam
Answer:
Given, length of the beam = 9 m
Width of the beam = 50 cm = 50/100 m = 0.5 m
Depth of the beam = 20 cm = 20/100 = 0.2 cm
So, the volume of the beam = 9 * 0.5 * 0.2 = 0.9 m3
Now, total weight of the wood if wood weight is 30 kg/m3 = 30 * 0.9 = 27 kg
