~RUMUS~
a. Volume Prisma Segitiga = 1/2 x a x t x t.prisma

Diketahui:
a = 8cm
t = 6cm
t.prisma = 10cm
Maka, volume

= 1/2 x 8 x 6 x 10
= 1/2 x 48 x 10
= 1/2 x 480
= 240cm³

b. 1/2 x 21 x 10 x 12
= 1/2 x 210 x 12
= 1/2 x 2.520
= 1.260cm³

c. Mencari tinggi = Volume : 1/2 x a x t (luas alas)
= 140 : 1/2 x 4 x 5
= 140 : 1/2 x 20
= 140 : 10
= 14cm

d. 1.750 : 1/2 x 14 x 25
= 1.750 : 1/2 x 350
= 1.750 : 175
= 10cm
semoga membantu...
