120 pixel - (100%-70%) = 120 - 30%= 84 pixel.
84 pixel + 30 pixel = 114 pixel.
120 pixel - (100% - 30%) = 120 - 70%= 36 pixel.
36 pixel + 5 x 7pixel = 36 + 35 = 71 pixel.
100% de 120 pixel=120 pixel.
120 pixel + 3 x ( 10 + 2 x 7) = 120 + 72 pixel= 192 pixel.

0,23x0,75x0,3 = 0,05175dm³ (volume de notre lingot d'or).
0,05175 x 19,3kg fait environ 1 kg (masse du lingot d'or)
1kg = 1000 grammes.
18 x 1000 = 18000€
