A small terrace at a flat football ground has 15 steps, each of which is 50 m long and built of solid concrete. Each step has a rise of \(\frac{1}{4}\) m and a tread of \(\frac{1}{2}\) m.Calculate the total volume of concrete required to built the terrace.
Note: You cannot build a step in midair. You have to fill the air beneath it.
