A cubic box has a 0.5 meter side. Find the mass of air in the box in kilograms. (1 Liter of air has a mass of 1.3 g). * m = 0.1625 kg
m = 162.5 kg
m = 16.25 kg
m = 16 kg

A cubic box has a 0.5 meter side. Find the volume of air in the box in a liter? *

V = 2.5 L
V = 0.125 L
V = 125 L
V = 12.5 L

Explanation:

Given

The length of the box is

1 liter of air has a mass of 1.3 gm

So, the density of air is

The volume of the box is

Mass of air in the box is
