Prisma Tegak Segitiga

==============================

==============================

Rumus luas alas segitiga = 1/2 × a × t

Rumus volume prisma = LA × T

==============================

1. LA = 1/2 × 28 × 21

LA = 1 × 14 × 21

LA = 14 × 21

LA = 294 cm²

V = 294 cm² × 32 cm

V = 9.408 cm³

B. LA = 1/2 × 48 × 25

LA = 1 × 24 × 25

LA = 24 × 25

LA = 600 cm²

V = 600 × 50

V = 3600 cm³

C. LA = 1/2 × 32 × 28

LA = 1 × 16 × 28

LA = 448 cm²

V = 448 cm² × 46

V = 20.608 cm³

D. LA = 1/2 × 24 × 32

LA = 1 × 12 × 32

LA = 384 cm²

V = 384 × 35

V = 13.440 cm³

E. LA = 1/2 × 22 × 26

LA = 1 × 11 × 26

LA = 286 cm²

V = 286 × 54

V = 15.444 cm³

F. LA = 1/2 × 20 × 10

LA = 1 × 10 × 10

LA = 100 cm²

V = 100 × 36

V = 3.600 cm³

================================
