Question

Volumul unei piramide hexagonale regulate cu muchia bazei si inaltimea de 6cm este egal cu .... cm cubi

Answer 1

aria bazei este= 3I²√3/2=3·6²√3/2=54√3
volumul=(aria bazei·inaltimea)/3=(54√3·6)/3=108√3

Answer 2

[tex]V= \frac{Ab*h}{3}= \frac{54 \sqrt{3}*6 }{3}=108 \sqrt{3} cm^{3} \\ Ab= \frac{3l^2 \sqrt{3} }{2} = \frac{3*36 \sqrt{3} }{2} =54 \sqrt{3} [/tex]
