Question

Uma pirâmide de base quadrada de lado 6 m, tem altura igual a 6 m também. O volume dessa pirâmide, em m³ é: A) 216 B) 108 C) 81 D) 72

Answer 1

$\large\boxed{\begin{array}{l}\underline{\sf C\acute alculo\,da\,\acute area\,da\,base}\\\rm B=\ell^2\\\rm b=6^2\\\rm B=36\,m^2\\\underline{\sf C\acute alculo\,do\,volume\!:}\\\rm V=\dfrac{1}{3}\cdot B\cdot h\\\\\rm V=\dfrac{1}{\backslash\!\!\!3}\cdot36\cdot\backslash\!\!\!6^2\\\\\rm V=2\cdot36\\\rm V=72\,m^3\\\huge\boxed{\boxed{\boxed{\boxed{\rm\green{\dagger}\red{\maltese}~\blue{alternativa~D}}}}}\end{array}}$
