Question

15. A beam 9 m long, 50 cm wide, and 20 cm deep is made of wood which weighs 30 kg per m³, find the weight of the beam.​

Answer 1

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
