@sujamait said:A small terrace at a football ground comprises 15 steps, each of which is 50 m wide and is built of solid concrete. Each step rises to 0.25 m and a length of 0.5 m. Calculate the total volume of concrete required to the build the terrace.OPTIONS1) 750 cc 2) 650 cc 3) 550 cc 4) None of these
option 1 = 750
15 (lbh) + 14 (lbh)+ ..........1(lbh) = lbh 15 *16/2 =7.5 m^3
15 (lbh) + 14 (lbh)+ ..........1(lbh) = lbh 15 *16/2 =7.5 m^3
