A residential foundation in Hawaii requires a moisture barrier. The foundation wall is 150 linear feet with an average height of 4 feet. If the moisture barrier material costs $2.25 per square foot, what is the total material cost?
Correct Answer
C) $1,350
Area = 150 ft × 4 ft = 600 sq ft. Total cost = 600 × $2.25 = $1,350.
Why This Is the Correct Answer
Area = 150 ft × 4 ft = 600 sq ft. Total cost = 600 × $2.25 = $1,350.
