I want to build a pricing matrix that is for items priced per square foot, matrix is in inches. rows 1-30, columns 1-30. The returned result is calculated by the simple formula [(number in cell of column A) x (number in cell of row 1)/144] x 16. That will give me 16 dollar per square foot price. Would like numbers to be 2 decimals with rounding. How does one automate this type of matrix generation? I've looked and looked... all advice is greatly appreciated-excel n00b
