Project Details
| Item | Value |
|---|---|
| Number of Windows | 10 |
| Width | 4 ft |
| Height | 5 ft |
| Cost Per Square Foot | $25 |
| Installation Cost | $1,200 |
Step 1: Calculate Total Area
Total Area = 10 × 4 × 5
Total Area = 200 sq ft
Step 2: Calculate Material Cost
Material Cost = 200 × $25
Material Cost = $5,000
Step 3: Calculate Total Cost
Total Cost = $5,000 + $1,200
Total Cost = $6,200
