400 – 8 = 392 (total length of 4 short pieces)

392/4 = 98 (length of 1 short piece)

98 + 8 = 106 (the length of the long piece)

Ans : 106 cm.

Length of each short piece -> u

Length of long piece -> u + 8

Total: 3u + (u + 8) = 400

4u + 8 = 400

4u = 392

u = 98

Length of the long piece -> (u + 8) = 98 + 8 = 106 cm
