Question

conhecendo o perimetro da base de um cubo Pb=16 cm determinar a) aresta b)área total

Answer 1

a) $\text{Perimetro da base}=4\times\text{Aresta}$

$16=4\times\text{Aresta}$

$\text{Aresta}=4~\text{cm}$

b) $\text{Area total}=6\times(\text{Aresta})^2$

$\text{Area total}=6\times4^2=6\cdot16=96~\text{cm}^2$.
