1. **State the problem:** Calculate the product for each item and then find the total sum. 2. **Calculate each product:** - Tuyuox ppr 12 × 4500 = $12 \times 4500 = 54000$ - Tuyuox PVC 110 5 × 12000 = $5 \times 12000 = 60000$ - Tuyuox PVC 63 4 = 36000 (already given) - Coude PVC 110 4 × 1500 = $4 \times 1500 = 6000$ - Coude ppr 30 × 500 = $30 \times 500 = 15000$ - Coude PVC 63 10 × 1000 = $10 \times 1000 = 10000$ - Tee 63 5 × 1200 = $5 \times 1200 = 6000$ - Tee ppr 13 × 600 = $13 \times 600 = 7800$ - Tee PVC 110 2 × 1500 = $2 \times 1500 = 3000$ - Coude adapter 14 × 800 = $14 \times 800 = 11200$ - Macho ppr 6 × 500 = $6 \times 500 = 3000$ - Colle tanqite 1 × 8000 = $1 \times 8000 = 8000$ - Coude merranger 2 × 5000 = $2 \times 5000 = 10000$ - Macho courbe 6 × 1000 = $6 \times 1000 = 6000$ 3. **Sum all results:** $$54000 + 60000 + 36000 + 6000 + 15000 + 10000 + 6000 + 7800 + 3000 + 11200 + 3000 + 8000 + 10000 + 6000 = 161000$$ 4. **Final answer:** The total sum is **161000**. This completes the calculation for each item and the total.
