Answer» A small terrace at a football ground comprises $15$ steps each of which is $50 m$ long and built of solid concrete. Each step has a rise of $4 / 1 m$ and a tread of $2 / 1 m .$ Calculate the total volume of concrete required to build the terrace. [Hint : Volume of concrete required to bulid the first step $= \frac{1}{4} \times \frac{1}{2} \times 50 m^{3}$ ]
