Question

a) Calcule o volume de uma pirâmide quadrangular com aresta da base igual a 3 cm e
altura é de 6 cm.

Answer 1

$\boxed{\sf{Volume~da~Pir\hat{a}mide}}\\\huge\boxed{\boxed{\boxed{\boxed{\sf{V=\dfrac{1}{3}\cdot B\cdot H}}}}}$

$\boxed{\begin{array}{c}\sf{B\longrightarrow \acute{a}rea~da~base}\\\sf{H\longrightarrow~altura}\end{array}}$

$\sf{B=3^2=9~cm^2}\\\sf{V=B\cdot H}\\\sf{V=\dfrac{1}{\diagdown\!\!\!3}\cdot\diagdown\!\!\!9\cdot6}\\\sf{V=3\cdot6}\\\huge\boxed{\boxed{\boxed{\boxed{\sf{V=18~cm^3}}}}}$
