Let's calculate the volume V of a barrel using the following formula:

V = π·R²·H,

where R and H are the radius and the height of a barrel respectfully. So,

V = π·(D/2)²·H = π·(32[inch]/2)²·67[inch] = 17152π [inch³] ≈ 53884.597 [inch³].

Therefore, there can be stored about 53884.597 cubic inches of waste.
