Question

O prisma triunghiulara regulata are fetele laterale patrate cu latura de radical din 2 cm.Calculati aria laterala si volumul prismei.

Answer 1

aria laterala= 3*$l^{2}$= 3*$\sqrt{2} ^{2}$=3*2=6 $cm^{2}$

Volumul= Ab*h(aria bazei ori inaltimea= $\frac{ \sqrt{3} }{4} * l^{3}$=$\frac{ \sqrt{3} }{4}$ * 2$\sqrt{2}$=$\frac{ \sqrt{6}}{2}$
