CÁLCULO DE ÁREAS.

Es la suma total del material utilizado para construir mi lapicero.
pieza 1 --> b x a = 6 x 10= 60 cm2 + b x a = 4 x 5 = 20 cm2: TOTAL : 20 + 60 = 80 cm2
pieza 2 --> b x a = 6 x 10 = 60 cm2
pieza 3 --> b x a = 6 x 5 = 30 cm2 + b x a / 2 = 4 x 5 / 2 = 10 cm2: TOTAL : 40 cm2
pieza 4 --> b x a = 6 x 10 = 60 cm2 + b x a = 4 x 5 = 20 cm2: TOTAL : 80 cm2
pieza 5 --> b x a = 6 x 10 = 60 cm2 + b x a /2 = 4 x 5 / 2 = 10 cm2: TOTAL : 60 + 10 = 70 cm2
pieza 6 --> b x a = 10 x 10 = 100 cm2

SUMA DE LAS AREAS = 430 CM2

It is the total sum of the material used to build my pencil holder.
