1)volume triangle d'or
= (3)/4 * L² * 0.2
= (3) * (1/4) * L² * (2/10)
= (3) * L² * (2/10)*(1/4)
= (3) * L² * (2*1)/(10*4)
= (3) * L² * (1/20)
= (3)/20 * L²
masse mor
= (3)/20 * L² * 19.3
= (3) * L² * (19.3/20)
= (3) * L² * (193/200)
= (193/200)(3) * L² grammes
prixor
= (193/200)(3) * L² * 40
= (3) * L² * 40* (193/200)
= (3) * L² * (40*193)/200
= (3) * L² * (193/5)
= (193/5)* 3 * L² euros
Voilà
