Adhesive and grout quantities are estimates based on the coverage, joint depth, and density values you supplied above — they are not derived from a cited standard, since these figures vary by product. Adjust them to match your chosen materials.
The diagram shows tiles to scale, including cut tiles at the edges, but the total quantity is calculated from area, not a count of the tiles drawn.
