Question

QUANTOS METROS CÚBICOS HÁ EM 8/5 DECÂMETROS CÚBICOS?

Answer 1

O prefixo $\text{"da"}$ equivale a $10^{1}=10.$


Sendo assim,

$\frac{8}{5}\text{ dam}^{3}\\ \\ =\frac{8}{5}\cdot (10 \text{ m})^{3}\\ \\ =\frac{8}{5}\cdot 10^{3}\text{ m}^{3}\\ \\ =\frac{8}{5}\cdot 1\,000\text{ m}^{3}\\ \\ =8\cdot \frac{1\,000}{5}\text{ m}^{3}\\ \\ =8\cdot 200\text{ m}^{3}\\ \\ =1\,600\text{ m}^{3}$
