Tolong bantu ya yg no 2,3,dan 5

[tex]volume \: prisma \: = \: luas \: alas \: \times tinggi \: volue \: = \\ [/tex]
a.= alas , t.= tinggi

2). volume= (1/2 × a. segi3× t. segi3)× t.prisma
volume =(1/2 ×16×12) ×14
= 96 ×14
volume = 1.344 cm3

3). volume = (1/2 × a. segi3× t. segi3)× t.prisma
volume = (1/2 × 28 ×26) ×35
= 364 × 35
volume = 12.740 cm3

5). I. luas jajargenjang
=2× 1/2×a×t
=2×1/2×16×8
=2×64 =128 cm2

II. luas segitiga
=1/2×a×t
=1/2×12×9
=6×9= 54 cm2
luas= bangun I +bangun II
luas=128 + 54 =182 cm2

smga bsa mmbantu :')
