The given pieces? You mean the 5 views? Those are 5 views of a single piece/object, which is formed by fusing several small cubes. Take 2 cubes,...

I agree. Although there's something not quite right with 4 and 5. If you see a rectangle that's 2 "fused" cubes. If there is a line in the middle,...

That's what you need to figure out to determine what the last projection is. I would start with grouping the views into pairs (2 directions for each...

I think these are 5 projections of a 3D object along one of the axes, and we need to draw the last one.

Do you have access to historical data? Previous reports? Any additional constraints? Do you need to recover a lost report knowing only that the ratio...

I don't see why we need to assume this. If all streets are straight and all intersections are 90 degrees we get a contradiction: Main and Rt 35 are...

Just make sure that only "Clay Ave and Rt 35 are straight and perpendicular to one another." The rest could be curved, slanted, etc.

The 3 angles marked by X are not the same 3 angles described as equal in the post. Please clarify.

Not quite correct. You need to carefully write out the result of multiplication.

Looks good. How do we get a simple equation from this?

Yes, this is a more precise way to describe the 2 equations :)

If you can think of a vector that lies on the X axis you can use the formula for calculating the angle between 2 vectors.

d(a)=d(b) doesn't make sense. 120m+d(a)=d(b) does. Do you understand where it comes from?

Why does it have to be dynamic? Compared to sizes of other assets (images, sound files) an array like that takes up very little space.

Ok, I think I understand. In order to calculate the total area you don't need an exact sketch. You need to know what kind of shapes you are dealing...

Looks like you have -36 twice instead of +36 and -36.
