a 125

b 225

c 550

d 575

Answer 1

$\boxed{\begin{array}{l}\underline{\rm c\acute alculo~da~\acute area~da~base:}\\\sf B=5^2=25~m^2\\\underline{\rm c\acute alculo~do~volume~da~pir\hat amide:}\\\sf V=\dfrac{1}{3}\cdot B\cdot H\\\sf V=\dfrac{1}{\diagdown\!\!\!3}\cdot25\cdot\diagdown\!\!\!\!\!\!15^5\\\sf V=25\cdot5\\\sf V=125~m^3\end{array}}\blue{\checkmark}$
