32.5 kg of air
Explanation:
To calculate the mass of the air, we use the density formula:
density = mass / volume
mass = density × volume
density of air = 1.3 kg/m³
volume = 5 × 3 × 2 = 25 m³
mass of the air = 1.3 kg/m³ × 25 m³
mass of the air = 32.5 kg

None. We already have more than we need ... provided only that the lane is on Earth.
Weight = (mass) (gravity).
On Earth, 'gravity' = 9.8 m/s^2.
Weight of the ball =
(4.5 kg) (9.8 m/s^2).= 44.1 newtons.
(roughly 9.9 pounds)
