2 retained component records. These tables cover selected readable outlines, not the whole job. Mass and weight are gross estimates before sink and fixture deductions.
What was checked and what is still missing
Compared with the paper
Folded surround top35.75 ×6.25 and two52 ×6.25 side returns match perspective annotations.
Part quantity top1 + sides2 preserved; parent folded perspective is not an extra part.
Needs confirmation
Large surround and long raised panel remain unresolved; several dimensions do not establish a unique closed contour.
Long-panel shoulder sum and overall reading require reconciliation; do not infer closure from image proportions.
Corner mitre/overlap and attachment details missing.
TP6610 density is proxy.
The source images were visually reviewed; handwriting and field dimensions are not independently verified. Actual support positions and connection capacities are also unconfirmed.
Assembly sketches join only faces supported by the drawing. Other pieces are grouped as sets. These are reconstructed schematics, not AutoCAD exports.

Thickness and density used in this table
Folded surround top face: 20 mm drawing reading; 2400 kg/m³ (Assumed study value).
Folded surround two side faces: 20 mm drawing reading; 2400 kg/m³ (Assumed study value).
Per-piece gross estimates. Sink and fixture openings are not deducted. Blank results need missing inputs; support examples may use separate, labeled assumptions.
The drawn faces are shown together as an assembly. Individual panel sizes and quantities remain in the table; corner overlaps and allowances need confirmation.
Measurements & calculation steps
Folded surround top face
length: 35.75 in · depth: 6.25 in
A = (35.75 × 6.25) in² × 0.0254² = 0.144 m² V = A × 0.02 = 0.00288 m³ ρ = 2,400 kg/m³ · Assumed study value m = ρV ≈ 6.92 kg Fg = mg ≈ 67.9 N
Face dimensions read from parent perspective assembly. Corner overlap/datum unknown; nominal gross face only.
Folded surround two side faces
height: 52 in · depth: 6.25 in
A = (52 × 6.25) in² × 0.0254² = 0.210 m² V = A × 0.02 = 0.00419 m³ ρ = 2,400 kg/m³ · Assumed study value m = ρV ≈ 10.1 kg Fg = mg ≈ 98.7 N
Face dimensions read from parent perspective assembly. Corner overlap/datum unknown; nominal gross face only.
WHY THE CALCULATIONS MATTER
Understand the material before planning the job.
Area and thickness determine stone volume. Density turns that into an estimated mass, and gravity gives its weight. These quantities support planning and discussion with the family business; supports, handling and installation need fabricator or qualified professional review.
Area → volume
A = L × D, or add rectangle areas V = A × t 1 in = 0.0254 m
Table results are per component; quantity is shown separately. Sink and fitting templates remain notes until confirmed. Grouping does not combine different rooms or alternative sheet versions into one slab.
Volume → mass → weight
m = ρV Fg = mg g = 9.81 m/s²
Mass uses kilograms and weight uses newtons. A blank result means thickness or density is unconfirmed. Density assumptions and provisional readings remain identified in the calculation notes.

No product-specific supplier density verified. 2,400 kg/m³ is an editable study assumption, not a measured value.
