Prime Cost = Raw Materials + Direct Labor. The prime cost of a single bed frame is ($6,500 + $750) / 10, or $72.50. In order to generate a profit, the company must sell each frame for more than $72.50.
Do the math. You probably know how to calculate the square footage of a simple room without any funny shapes. Just break out your measuring tapeâor a laser measureâto get its length and width. Multiply the width by the length and voila! You have the square footage. Say a room is 20 feet wide by 13 feet long, then 20 x 13 = 260 square feet. How to calculate square feet.
One square foot is one foot wide by one foo â¦ t tall (1 ft x 1 ft = 1 sq ft). Actually you can't measure how many feet are in a square foot since one is distance and the other area. for example, a rectangle that is 0.25ft by 4 ft would have a area of one square foot and a perimeter of 8.5 feet.ne cubic yard of decomposed granite will cover one-hundred-eight (108) square feet in a three-(3)-inch layer. But we need to double-check our work. So taking the number one-hundred-eight (108), we will divide it by four to find out how many cubic feet of granite there are, and we reach the number twenty-seven (27).
