Final answer:
To estimate the cost of a new house, multiply the square footage by the average construction cost per square foot.
Step-by-step explanation:
When estimating the cost of a new house, you can use the formula: cost = square footage × average construction cost per square foot. By multiplying the square footage of the house by the average construction cost per square foot of similar houses, you will get an estimate of the total cost of the new house. For example, if the square footage is 1600 square feet and the average construction cost per square foot is $200, then the estimated cost would be $320,000.
