The body

The body has dimensions of 2m 2dm and 10 cm. It weighs 28 kg. What is its density?

Correct result:

h =  700 kg/m3

Solution:

a=2 m b=2 dm m=2/10  m=0.2 m c=10 cm m=10/100  m=0.1 m m=28 kg  V=a b c=2 0.2 0.1=125=0.04 m3  h=m/V=28/0.04=700 kg/m3



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