if decking cost 3.25 per square feet how much would it cost to build a deck that is 25 feet by 20 feet
Zepler [3.9K]

The cost to build a deck that is 25 feet by 20 feet is 1625

<h3>How to determine the cost?</h3>

The given parameters are:

Cost per square feet = 3.25

Dimensions = 25 feet by 20 feet

The cost to build the deck is calculated as

Cost = Cost per square feet * Product of dimensions

So, we have

Cost = 3.25 * 25 * 20

Evaluate

Cost = 1625

Hence, the cost to build a deck that is 25 feet by 20 feet is 1625
