算法是 (長/30)*(寬/30)
所以 45cm*45cm = 1.5*1.5 = 2.25才
不過有時會有最小單位,例如不足半才以半才計算,
例如 30cm*24cm = 1 * 0.8 以1才計算
36cm*24cm = 1.2 * 0.8 = 0.96 以1才計算
30cm*45cm = 1 * 1.5 以1.5才計算
30cm*51cm = 1 * 1.7 以2才計算
通常都是每面分開計算最小才數,不是全部加起來才以最小單位計算,
例如 60*45*45的尺寸,最小才數為半才的話:
45*45 = 2.25 => 2.5 x 2面 = 5
60*45 = 3 => 3 x 3面 = 9
所以總共是14才,而非 2.25*2 + 3*3 = 13.5才,
所以如果是算才數的,最好問清楚,也可以自己考慮一下尺寸,
避免為了計算錯誤而多花錢!!
※ 引述《trimos (moss)》之銘言:
: 想請問一下
: 一才是30*30
: 90*30 = 3才
: 那45*45是不是4才?
: 90*30*30=11才
: 90*45*45是算幾才?
: 一般而言1才5mm價錢是落在哪裡
: 10mm是5mm的2倍還是2倍以上
: 謝謝
