Vi du thuc te (Cua lua 2 canh): Neu o cho co chieu ngang lot long la 3000mm.



1. Tong do tru co dinh (Khung bao ngoai): $25\text{mm} (\text{Trai}) + 25\text{mm} (\text{Phai}) = 50\text{mm}$.

2. Khoang trong con lai cho hai canh: $3000 - 50 = 2950\text{mm}$.

3. Do chong khit giua hai canh: 50mm.

4. Tong chieu rong thuc te hai canh (chua ke chong khit): $2950 - 50 = 2900\text{mm}$.
