Question

Aflati volumul unei piramide patrulatere regulate stiind ca aria bazei(Ab)=36 iar inaltimea (h) =$\frac{6 \sqrt{15} }{3}$

Answer 1

V=(36 x6√15/3 ) /3=24√5 

Answer 2

$V= \frac{Ab * h}{3} = \frac{36* \frac{6 \sqrt{15} }{3} }{3}= \frac{12*6 \sqrt{15} }{3} = \frac{72 \sqrt{15} }{3}= 24 \sqrt{15}$
