How many 20 × 20 × 20 in boxes fit in a 7.5 t truck?

20 × 20 × 20 in boxes of 508 × 508 × 508 mm (also called 4.6 cubic foot cube boxes) in a 7.5-tonne box truck — inner dimensions 6,200 × 2,450 × 2,400 mm. Calculated by the Cubestow engine on 2026-09-08.

The answer in detail

A 20 in cube — used as a master carton for lightweight bulky goods (pillows, packaging, toys).

Typical 7.5 t rigid with a 6.2 m body. Payload is limited to roughly 2.8 t once the body and tail-lift are accounted for, so heavy cargo fills the weight allowance long before the space.

The simple grid estimate is 12 along the length × 4 across × 4 high = 192. Here no mixed pattern beats the best uniform grid, so the engine's plan is exactly that grid (192).

Frequently asked

How many 20 × 20 × 20 in boxes fit in a 7.5 t truck?

192 20 × 20 × 20 in boxes of 508 × 508 × 508 mm fit in a 7.5 t truck (inner dimensions 6,200 × 2,450 × 2,400 mm), boxes may be laid on any side. That uses 69% of the 36.5 m³ available and weighs about 2,304 kg.

What are the inner dimensions of a 7.5 t truck?

Typical inner dimensions are 6,200 mm long, 2,450 mm wide and 2,400 mm high (244.1 × 96.5 × 94.5 in), giving 36.5 m³ of space and a rated payload of about 2,800 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?

192 × 12 kg ≈ 2,304 kg, which is 82% of the 2,800 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.

Other cargo in a 7.5 t truck

Assumptions. Cargo is modelled as rigid rectangular boxes with the outer dimensions above; the container's typical inner dimensions and rated payload are used; every box needs at least 80% of its base supported; no dunnage, straps or door clearance are reserved. The plan is one of many optimal or near-optimal arrangements — the engine's plan was checked for overlaps, support, orientation and weight, and the count is what it achieved within 1.4 s of search. Real containers vary by manufacturer; measure yours for tight loads.
