Question

What mass of water will fill a tank that is 100.0 cm long, 50.0 cm wide, and 30.0 cm high? Express the answer in grams.

Answer 1

$calculate\ mass\ from\ formula\ for\ density:\\\\ density=volume*mass\\ mass=\frac{density}{volume}\\\\ volume=width*length*height\\ volume=100*50*30=150000cm^3=0,15m^3\\\\ density\ of\ water=\ 999.9720 \frac{kg}{m^3} \\\\mass=0,15*999.9720=149,9958kg=149995,8grams\\\\ Answer\ is\ :\\water\ which\ weight\ is\ equal\ to\ 149995,8grams.$
