Sumit constructs a wall working in a special way and takes 12 days to complete it. If S_{n} is the length of the wall (in m) that he constructs on the nth day, then
S_{n} = 2n, 0 ≤ n ≤ 4
S_{n} = 8, for n = 5
S_{n} = 3n  7, 6 ≤ n ≤ 12
Find the total length of the wall he constructs in the first 10 days.
