[REQ][HELP]Adding equally spaced text boxes

[kirobo]

I want to create 4 text boxes of width 300 which are equally spaced. Can someone please help?

$x = (10*$i) + 300;
$y = $x * 100;
I'm trying to do it like this:
shape = $currentSlide->createRichTextShape()
                            ->setHeight(100)
                            ->setWidth(300)
                            ->setOffsetX($x)
                            ->setOffsetY($y);
