Let width = x

Let length = 2x

Let height = 3x

Then the sum of all its edges is

4(2x) + 4x + 4(3x) = 360

Solve for x.

I'll help you understand math!

2:1:3 means there are 6 total parts. 360/6 = 60

If the height is 3 of those parts, 3(60) = 180 cm

It doesn't ask, but the length is 2(60) = 120 and the width is the last 60.
