How many 20 × 20 × 20 in boxes fit in a 12 t truck?
20 × 20 × 20 in boxes of 508 × 508 × 508 mm (also called 4.6 cubic foot cube boxes) in a 12-tonne box truck — inner dimensions 7,300 × 2,480 × 2,500 mm. Calculated by the Cubestow engine on 2026-09-08.
Boxes may be laid on any side. 65% of the space used, 4 layers high, about 2,688 kg (49% of payload). Open this load in the 3D planner →

The answer in detail
A 20 in cube — used as a master carton for lightweight bulky goods (pillows, packaging, toys).
A 7.3 m rigid body with around 5.5 t of payload — the usual size for regional pallet distribution.
The simple grid estimate is 14 along the length × 4 across × 4 high = 224. Here no mixed pattern beats the best uniform grid, so the engine's plan is exactly that grid (224).

Frequently asked
How many 20 × 20 × 20 in boxes fit in a 12 t truck?
224 20 × 20 × 20 in boxes of 508 × 508 × 508 mm fit in a 12 t truck (inner dimensions 7,300 × 2,480 × 2,500 mm), boxes may be laid on any side. That uses 65% of the 45.3 m³ available and weighs about 2,688 kg.
What are the inner dimensions of a 12 t truck?
Typical inner dimensions are 7,300 mm long, 2,480 mm wide and 2,500 mm high (287.4 × 97.6 × 98.4 in), giving 45.3 m³ of space and a rated payload of about 5,500 kg. Individual units vary by a few centimetres, so check the actual box for tight loads.
How much does a full load of 20 × 20 × 20 in boxes weigh?
224 × 12 kg ≈ 2,688 kg, which is 49% of the 5,500 kg payload — so this load is limited by space, not weight.
How was this number calculated?
By running the Cubestow 3D load-planning engine on the exact dimensions above, allowing all six orientations, stacking with at least 80% base support and the container's payload limit, then re-validating the plan for overlaps, support and weight. Real loads leave room for dunnage, door clearance and uneven cartons, so treat the figure as the practical maximum.
