First, let's find out how many man-days it takes to build a 1 meter length of the wall.

72 men can build 280 m in 21 days, so the total man-days is 72 men * 21 days = 1512 man-days.

Therefore, it takes 1512 man-days to build 280 m, so to build 1 m, it would take 1512 man-days / 280 m = 5.4 man-day Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
