Sure. This is from a UK model.
The actual macbook box is 30.5cm wide, 22cm deep and 6.25cm high.
The shipping carton they come in (a very clever cantilevered bit of cardboard wizardry) is 33.75cm wide, 24.5cm deep and 10.25cm high.
FWIW, in the shipping carton the weight is declared as 1.95kg.
Hope that helps!
