You divide the shape into smaller shapes you can calculate, like rectangles and triangles. If the shape is irregular, you have to approximate, for example by dividing it into many narrow rectangles. This technique is called "integration".
in the 120s the anceient lords declard that this very unusual shape shall be called rectangular prism
Because Clay falls off of the edge off the edge of the cavern in different places around the cavern, due to weathering. Then, as limestone is being brought into the cave, also by weathering, clay goes throught the weathering process and then though becomes in an unusual shape.
Usually, you divide by the area of a single tile. But this may not work if the tiles have an unusual shape, or if you need fractional tiles to cover the entire area.
Assuming "liths" is an unusual way of spelling lengths, you cannot because a quadrilateral is not a rigid shape. It can be deformed into a quadrilateral with the same sides but a different area. This can be illustrated by thinking of a square deforming into a rhombus. Same sides but different area.

The deserts, coastline, and oases of Arabia helped shape the Arab way of life.
