4dm³ = 4 * 10^-3m³

6 * 10^-3 dm³ = 6 * 10^-6 m³

/\V = Vo * gama * /\T
6*10^-6 = 4*10^-3 * gama * 5*10^2

6 * 10^-6 = 20*10^-1 * gama

6 * 10^-6 / 20*10^-1 = gama

6 * 10^1 * 10^-6 / 20 = gama

60 * 10^-6 / 20 = gama

********************************************************************
gama = 3 * 10^-6 °C^-1 // Coef. Dilatação Volumétrica

Coeficiente de Dilatação Linear = alpha = gama/3

alpha = 3 * 10^-6 / 3 = 1 * 10^-6 °C^-1
