Question

O volume total de um cubo cuja diagonal da face tenha medida...
$3 \sqrt{2}$
​

Answer 1

Resposta:

$d = l \sqrt{2} \\ 3 \sqrt{2} = l \sqrt{2} \\ l = \frac{3 \sqrt{2} }{ \sqrt{2} } \times \frac{ \sqrt{2} }{ \sqrt{2} } = \frac{3 \times 2}{2} = \frac{6}{2} = 3 \\ volume \: = \: {l}^{3} \\ volume \: = \: {3}^{3} \\ volume \: = \: 27$
