I've been asked by a friend to build a planter box made with Northern White Cedar. I was given dimensions of the box as 61" x 18" x 26.5". There were no indications of length height and width, but obviously the box will be 61" long. Without benefit of W and H indicators, what would be the protocol for reading 61" x 18" x 26.5"? Should the height be 26.5 or is that the width? My friend is unavailable for consultation on this. The planter will hold LLEX Crenata (a species of Japanese Holly, to 4 feet high.
Thanks.
