Building a fence...

[wrang]

Everything is at a standstill but I need your help
I am planning to build a fence with a height of 180cm and a length of 25 meters. I was thinking of using planed 120x22 and 45x22mm with a 1cm gap between
How many planks do I need and per meter per unit???
Xm for 120mm
Xm for 45mm

Kind regards,

Approximately 143m of each dimension + waste if you don't buy them in 3.6m lengths

Thanks!!
Spill is not good since they must be thrown away anyway let's see what they have

You arrive at 143 if you calculate that you should have 120,plank,space,45-plank and then repeat this pattern. But I find it more likely that you want to repeat the pattern 120-plank, space, 45-plank, space. Otherwise, the wide and the narrow plank would be next to each other when you set the next repetition. Additionally, the figure becomes the number of groups you need, not the number of meters. So what you want is 120mm+10mm+45mm+10mm=185mm. The entire board is 25000mm. This means you will get 25000/185=135.135 groups. For each group, 1.8m of each type is needed. Therefore, I would say it will be a total of 135*1.8m = 243m of each type.
(If you set 135 groups without modifying the distances a little at the end, the board will be 24,975m, i.e., 25mm shorter than requested.)

143 is reached if you count that you should have 120,plank,space,45-plank and then repeat this pattern. But I find it more likely that you want to repeat the pattern 120-plank,space,45-plank,space. Otherwise, the wide and narrow plank end up next to each other when you set up the next repetition. Also, the number becomes how many groups you need and not the number of meters. So what you want is 120mm+10mm+45mm+10mm=185mm. The entire plank is 25000mm. This means you will get 25000/185=135.135 groups. For each group you need 1.8m of each kind. So I would say that it will be a total of 135*1.8m = 243m of each kind. (If you set 135 groups without modifying the spaces a little at the end, the plank becomes 24,975m, i.e., 25mm shorter than requested.)

Exactly
(120mm+10mm+45mm+10mm)
