Question

how do i find the dimensions of an object, the calculations, and the dimensions of a scaled object?

Answer 1

Dimensions are length, width, and height. We can't really use a tape measure in any more dimensions. You can also think of the dimensions as being x, y, and z, or forward, side, and up.
I don't really know how to answer How do I find calculations?
But a scaled object is some multiple bigger or smaller. Twice as big would be 2x, 2y, 2z.
