luas segitiga = 6 x (1/2 x 6 x 10) = 180
Lp Total = 180 + 1/6 akar 3 cm^2
=(6.6^2)/4.tan(180/6)
=216/4.tan 30
=54akar3 cm^2=93,5 cm^2
V=1/3.luas alas.t
=1/3.54akar3.8
=144akar3 cm^3
=249,4 cm^3
luas slimut=n.luas sisi tgak
=6.1/2.a.t
=3.6.8
=144 cm^2
luas prmukaan=luas alas+luas slimut
=54akar3+144
=237,5 cm^2
