Why does scale and setting geometry looks different?

Don’t take it, it was different usage. I ask, how do i scale the object, that was settled by geometry to make it look like it was seted by geometry? Like
I set geometry (4,4,4)
How do i change scale to make it look now as geometry (5,5,5).

var geom = new THREE.BoxBufferGeometry(4, 4, 4);
var mesh = new THREE.Mesh(geom, some_material);

The result is a box of 5 x 5 x 5.
The size you want divide by the size you have thus you’ll get the desired scaling value.
You want 5, you have 4, then 5 / 4 = 1.25.
