// At the end of this test, all boxes would be closed
}

Explanation:
Draw isometric projection Spatial axes of the item are represented as similarly willing to the drawing floor and same distances alongside the axes are drawn the same.
<h3>What is isometric projection?</h3>
Definition of isometric projection an axonometric projection wherein the 3 spatial axes of the item are represented as similarly willing to the drawing floor and same distances alongside the axes are drawn same.
An isometric view of an item may be received via way of means of selecting the viewing path such that the angles among the projections of the x, y, and z axes are all of the same, or 120°. For example, with a cube, that is achieved via way of means of first searching immediately toward one face.
