Answer 1

It seems that BVOT wants boxes with specific dimensions:

Ex: A4 paper width size = 29.7 cm and i want total (all column boxes = 27 cm) and box CCC width = 15 cm, AAA width = 5 cm and BBB width = 7 cm.

In this case it's easier to use tcbposter. A tcbposter is an initial regular distribution of columns and rows over which place boxes with reference to columns, rows and other boxes.

As desired boxes widths are not proportional, I've used a tcbposter with just two columns. Left box will be aligned to left and right boxes to the right. The middle box on first row will be placed xshifted from the left border.

Proposed dimensions don't allow space between columns, therefore I've reduced left box and first column right box get some separation between columns.
