Lift a Cube Cubes

Compare four documented cubes by their displayed weight and displayed Recommended Strength. This is a partial list, not a claim that every cube in the game has been recorded.

Direct answer

Wood starts at 2.1 kg; the documented set reaches Ice at 66.2 kg

Each value below was reviewed field by field on 12 September 2026. The official Roblox description confirms that farther cubes are heavier, but it does not publish these numbers.

What does Recommended Strength mean?

Recommended is a number displayed for a Cube, recorded separately from its weight. For example, the documented Wood labels are 2.1 kg and 6 Strength. Neither the official description nor the reviewed record proves a kilograms-to-Strength conversion or a universal hard minimum.

A 13 September community walkthrough (R07) reports that Cube readouts can change when the map refreshes. This site has not independently tested that behavior, so use the four dated records as examples and check your current on-screen labels.

Use the label as a planning reference, then test the Cube in your current game session. Compare all four checkpoints with your Strength →

Why payout and area say Unknown

The reviewed material did not establish a currency label or independently confirm every location. Unknown fields remain unknown instead of being replaced with guesses, zeroes or unlabeled numbers. The 12 September values have not been rechecked after the Update 1 listing.

Why the third record says Cooper Cube

The reviewed source consistently uses Cooper Cube in its table, gameplay-image caption and zone text. An exact-match check found no competing “Copper Cube” record for this game. Because this is not an official API field, corrections with a readable in-game capture are welcome.

Source and correction path

Record source R03 is a third-party gameplay snapshot reviewed by the site owner. It is not presented as developer documentation.

Record a Cube the list is missing

Use the current in-game label, not a guessed tier or an older guide. A name alone can be reported without a weight; a weight alone does not prove a Strength requirement. The note stays in your browser until you copy it, and copying does not submit a new site record.

Quick questions

Cube list FAQ

Is this the complete Lift a Cube cube list?

No. It contains four records that passed the current evidence review. More records will be added only when their fields can be checked.

Does 21 kg mean I need exactly 21 Strength?

No. Weight and displayed Recommended Strength are separate fields. For Cooper Cube, the documented labels are 21 kg and Recommended 206.

Why are cash rewards missing?

The visible currency was not confirmed. Publishing 35 or 69 without a verified currency would create an incomplete numeric claim.
