Question

aflati aria totala si volumul unei piramide patrulatere regulate cu aria bazei de 36cm(patrati), apotema de 6cm si inaltimea de 3radical3cm

Answer 1

A= 36⇒ l=√36=6cm
apo 6:2=3
At= Ab+Al
Al= 4x(lxh)/2=72
At= 36+72=108
V=36X3√3=36√3 

Answer 2

h=3√3cm
ap=6cm
Ab=36cm^2
Ab=l^2
l=6cm
V=Ab×h/3
V=36×3√3/3
V=36√3cm^3
At=Al+Ab
Al=Pb×ap/2
Pb=4l=24cm
Al=24×6/2=72cm^2
At=72+36
At=108cm^2
