Soal Nomor 3

Volume Prisma Segitiga

V = ½ × a × t × tp

V = ½ × 3 cm × 4 cm × 9 cm

V = 3 cm × 2 cm × 9 cm

V = 6 cm² × 9 cm

{ V = 54 cm³ }

Soal Nomor 4

Panjang Kerangka Prisma Trapesium

= 2( a¹ + a² + t + s ) + 4( tp )

= 2( 12 + 7 + 6 + 8 ) + 4( 14 )

= 2( 19 cm + 14 cm ) + 56 cm

= 2( 33 cm ) + 56 cm

= 66 cm + 56 cm

= 110 cm + 12 cm

= { 122 cm }

Volume Prisma

V = ½ × ( a¹ + a² ) × t × tp

V = ½ × 19 cm × 6 cm × 14 cm

V = 19 cm × 3 cm × 14 cm

V = 57 cm² × 14 cm

V = ( 57 × 10 ) + ( 57 × 4 )

V = 570 cm³ + 200 cm³ + 28 cm³

V = 770 cm³ + 28 cm³

{ V = 798 cm³ }
