how to calculate the price based on width and length

[Too Cool]

Here some examples based on 210€ / m width and 30€ / m².

Width: 1 m, Length: 5 m = 1 x €210,- + 5 x € 30,- = € 360,-

Width: 0,5 m, Length: 5 m = €105,- (0,5m x €210 = € 105,-) + €75,- (0,5 x 5 = 2,5 x € 30,- = € 75,-) = € 180,-

Width: 2 m, Length: 10 m = €420,- (2m x €210 = €420) + €600,- (2 x 10 = 20 x € 30,- = € 600,-) = € 1.020,-

Width: 0,25 m, Length: 10 m = €52,5 (0,25m x €210,-) + € 75,- (0,25 x 10 = 2,5 x €30,- = € 75,-) = € 127,50,-

Width: 0,7 m, Length: 6,85 m = €147,- (0,7m x €210,-) + € 144,- (0,7 x 6,85 = 4,8 x € 30,- = € 291,-

Width: 1,73 m, Length: 8,45 = € 363,3- (1,73m x €210,-) + €438,6 (1,73 x 8,45 = 14,62 x € 30,- = €438,6) = € 801,90,-

 

SO THE TOTAL WIDTH PRICE IS € 210,- BRUTTO. That means that if someone has ,10 m it is €210,- or is someone has 0,5 m (half of €210,- m) it is € 105,- or if someone has 2 m it is double (2 x € 210,-)!

THIS IS ALSO VALID FOR EACH SINGLE CM SO THAT EACH CM OF HEADER IS WORTH € 2,1!!!

 

EACH m² COSTS €30,- NO MATTER WHAT LENGTH / WIDTH THE SYSTEM HAS - SO THE SYSTEM ONLY NEEDS TO CALCULATE WIDTH x LENGTH TO GET THE TOTAL SURFACE AND MULTIPLY IT BY € 30,- AND ADD THE WIDTH TO IT WHICH IS €210,- / m (or €2,1 / cm)

 

How this can be done in presta shop?
