Question

va rog daca se poate sa.mi rezolvati aceasta problema: o prisma hexagonala are latura 6√3 si aria laterala 270√3.calculati:ap si volumul

Answer 1

Al = Pb x h
Pb = 6 x latura = 6 x 6 radical 3= 36 rad 3
270 rad 3 = 36 rad 3 x h
h= 270 rad 3 : 36 rad 3
h=15/2=7,5

volumul prismei = Ab x h 
Ab=3l²rad3/2=3 x (6rad 3)² x rad3/2=162 rad 3
Vp=162 rad 3 x 15/2=1215 rad 3
