Answer:
Given dimensions of room:
- length = 12 ft
 - width = 14 ft
 - height = 8 ft
 
Given cost of materials:
- floor tiles = $4 per ft²
 - wall & ceiling paint = $16 per 146 ft²
 
Total square feet of floor = length × width
 = 12 × 14
 = 168 ft²
Total cost of flooring = $4 × 168
 = $672.00
Total square feet to be painted = area of walls + area of ceiling
 = 2(12 × 8) + 2(14 × 8) + (12 × 14)
 = 584 ft²
Total cost of paint = (584 ÷ 146) × $16
 = $64.00
Total cost to tile and paint the room = $672 + $64
 = $736.00
