V = ½.a.t.tp

V = ½.12.16.9

V = 8 cm × 108 cm²

V = 864 cm³

Lp Prisma Segitiga

Lp = at + tp( a + t + s )

Lp = 12.16 + 9( 12 + 16 + 20 )

Lp = 192 cm² + 9 cm × 48 cm

Lp = 192 cm² + 432 cm²

Lp = 624 cm²

Answer 2

VP :

= (1/2(12(16(9)

= (1/2(12(144)

= (1/2(1.728)

= 1.728/2

= 864 CM³

LP :

= (12(16) + 9(12 + 16 + 20)

= 192 + 9(12 + 36)

= 192 + 9(48)

= 192 + 432

= 624 CM²
