Using this as a reference you can measure it two different ways. The top one assuming it's 39cm/1 in = one side, the bottom being end to end. If it's the first on, the cucumber is about 6 length which is the measurement you gave. But if it's assuming end to end, then the measurement becomes 4.66 times or about 7.1 inches length.
