A small terrace at a football ground comprises of 15 steps each of which is 50 m long and built of solid concrete. Each step has a rise of `1/4` m and a tread of `1/2` m. (see Figure). Calculate the total volume of concrete required to build the ter

A small terrace at a football ground comprises of 15 steps each of which is 50 m long and built of solid concrete . Each step has a rise of 1/4 m and a tread of 1/2 m ( ss fig ) .Caculate the total valoume of concrete required to build the terrace . [ Hint : volume of concrete required to build the first step = 1/4 xx 1/2 xx 50 m^(3) ]
