Question

Um cubo tem área toral de 96cm.qual é a medida da aresta do cubo?

Answer 1

$\Large\boxed{\begin{array}{l}\sf\underline{\acute Area~total~do~cubo}\\\huge\boxed{\boxed{\boxed{\boxed{\sf A_t=6\cdot\ell^2}}}}\end{array}}$

$\Large\boxed{\begin{array}{l}\tt dados\begin{cases}\sf A_t=96~cm^2\\\sf \ell=?\end{cases}\\\underline{\rm soluc_{\!\!,}\tilde ao:}\\\sf A_t=6\cdot\ell^2\\\sf 6\cdot \ell^2=96\\\sf \ell^2=\dfrac{96}{6}\\\sf\ell^2=16\\\sf \ell=\sqrt{16}\\\sf\ell=4~cm\end{array}}$

Answer 2

Resposta:  4cm

Explicação passo a passo:

a=√96/6

a=√16
