Question

A hot air balloon holds 3,249 cubic meters of helium. The density of helium is 0.1785 kilograms per cubic meter. How many kilograms of helium does the balloon contain, rounded to the nearest tenth of a kilogram?

1,873.4 kg

2,194.6 kg

2,721.2 kg

579.9 kg

Answer 1

volume is 1592 cubic meters
density is 0.1785 kg / cubic meter

mass is volume * density

when you do the multiplication, the two cubic meters units cancel out, leaving you with only kg as the unit.

Answer 2

so 1592*0.1785
