Question

Qual o volume de uma pirâmide quadrangular regular de aresta da base 5cm e altura 12cm?

Resposta: 100cm³​

Answer 1

$Volume_{piramide}~=~\dfrac{(Area~da~Base)~\times~Altura}{3}\\\\\\Volume_{piramide}~=~\dfrac{(Aresta^2)~\times~12}{3}\\\\\\Volume_{piramide}~=~\dfrac{(5^2)~\times~12}{3}\\\\\\Volume_{piramide}~=~\dfrac{25~\times~12}{3}\\\\\\Volume_{piramide}~=~\dfrac{300}{3}\\\\\\\boxed{Volume_{piramide}~=~100~cm^3}$

Answer 2

Qual o volume de uma pirâmide quadrangular regular de aresta da base 5 cm e altura 12 cm?

Explicação passo-a-passo:

Volume

V = Ab *h/3

V = 5^2 * 12/3 = 25 * 4 = 100 cm^3
