Brick wall

What is the weight of a solid brick wall that is 30 cm wide, 4 m long and 2 m high? The density of the brick is 1500 kg per cubic meter.

Correct result:

m =  3600 kg

Solution:

a=30 cm m=30/100  m=0.3 m b=4 m c=2 m  h=1500 kg/m3  V=a b c=0.3 4 2=125=2.4  m=h V=1500 2.4=3600 kg



We would be pleased if you find an error in the word problem, spelling mistakes, or inaccuracies and send it to us. Thank you!
