Question #528
One cubic metre of steel weighs approximately:
Metr sześcienny stali w przybliżeniu waży:
a
1000 kg
1000 kg
b
4.5 - 5.0 t
4,5 - 5,0 t
c
1.0 t
1,0 t
d
7.5 - 7.9 t
7,5 - 7,9 t
Correct answer
Why?
The density of steel (gęstość stali) is approximately 7850 kg/m³, so 1 m³ of steel weighs about 7.85 t. This falls within the 7.5 - 7.9 t range. A mass of 1000 kg corresponds approximately to 1 m³ of water, not steel.
