12.5 cubic feet. Assuming you meant 4 INCHES thick..
15ft is 5 yds, so 15ft x 15ft is the same as 5yds x 5yds which would equal 25 square yards.
That depends on the length and width of your construction.

It can be used, provided you know the maximum weight on vehicles on it. From experience, 30 ton trailers can run comfortably on a 200mm thick g-25 concrete mix..
Area = 15*25 = 375 square feet
25ft * 15ft = 375 ft2
It is all dependant on how thick the concrete is. You take the square footage and turn that into cubed feet (where the thickness comes in) if its 1" thick you multiply the square footage by.083, if its 2" thick you multiply by.17. To come up with this number you take the thickness say 3" and divide that by 12 (12 inches in a foot), so for 3 inches you get .25. So back to the question at hand, say your 30 square feet of concrete is 6 inches thick, your equation would look like this: 30 X .5 = 15. So 15 is your cubed footage. You then multiply this number by 150 which is the weight in pounds of 1 cubic foot of concrete. The number you come up with is 2,250. That is the amount in pounds of your 30 square feet of concrete assuming it is 6 inches thick.

Please clarify what linear measure you want to calculate: for example its length, width, diagonal, perimeter, etc.
To estimate the cost of flooring for a 15ft by 25ft room, first calculate the area, which is 375 square feet (15ft x 25ft). Flooring prices can vary widely based on material, installation, and location, typically ranging from $2 to $10 per square foot. Therefore, the total cost for materials and installation could range from approximately $750 to $3,750. It’s best to get quotes from local contractors for a more accurate estimate.
