Question from Tammie: What is the formula to calculate the following: I have a plate of steel that is 1/4" x 48" x 192" at a price of $15.23 per square foot |
Hi Tammie,
The cost is per square foot so you need to convert the measurements to feet. There are 12 inches in a foot so you need a piece that is 47.25/12 feet by 68.125/12 feet. That is
(47.25/12) × (68.125/12) = 22.3535 square feet.
At $15.23 per square foot that will cost
22.3535 × $15.23 = $340.44.
