Question

O prisma triunghiulara are latura bazei de 12 cm si muchia laterala de 10 cm . Calculati :
a) aria laterala a prismei
b) aria totala a prismei
c) volumul prisme

Answer 1

a) $A_{l}$=$P_{b}$·h=3·12·10=360
b)$A_{t}$=$A_{l}$+2$A_{b}$=360+2·36√3=360+72√3
$A_{b}$=l²√3/4=36√3
c) V=$A_{b}$·h=36√3·10=360√3
