I wouldn't think so since it doesn't explicitly state that you must spend a bonus action to activate the ability. Although that would make it technically superior (if only marginally) to giving an ally a plain old Bardic Inspiration die.

Cube of Force (Wondrous Item, Rare)
Table: Cube of Force
My question is this: When activating the button on the 5th side of the cube, does the cube prevent everything from entering it's area? Does that include things like breathable air? And natural light?
The cube has the ability to keep gasses, wind, and fog from penetrating its area, so I feel like that means its capable of excluding oxygen (or an otherwise breathable atmosphere) as well. Or at least it wouldn't allow new oxygen in.
But I'm just wondering if it was designed with the intent of keeping literally everything out, as the magic item suggests. On the surface, if it did keep everything out, one might think that's a bad thing. But, what if a warlock villain had such a cube (with the Devil's Sight invocation)?
Could they theoretically activate the cube's 5th side while another creature is within, say, 10ft of them and trap that creature in a space that's suddenly devoid of light and with limited oxygen?

|---|---|---|
| 1 | 1 | Gasses, wind, and fog can’t penetrate the cube. |

| 3 | 3 | Living matter can’t penetrate the cube. |
| 4 | 4 | Spell effects can’t penetrate the cube. |
| 5 | 5 | Nothing penetrates the cube (exception for walls, floors, and ceilings at your discretion). |
| 6 | 0 | Deactivate the cube. |

I think it's always been assumed that breathable air can pass through the walls of a wall of force or forcecage, because otherwise you'd have to pull up the suffocation rules and do math to determine how much air is already in there. Since cubes of force are basically those spells in item form, I'd say... it's up to you. The reddit link above says that there would be about 8 hours of air in such a cube, even if no new air enters. And since each charge lasts for 1 minute...
So, as evilly dramatic and cool it might be to suffocate someone in a pitch-black cube of force, it's likely not actually possible. Sorry.

No, they're separate abilities. They just use the same resource.
That makes sense.

OTOH, you could make a "cube of space" variant of the cube of force that sucks all the air in it into the Plane of Space...
