A=25cm, t=20cm, b=16cm, c=14cm , tentukan luas permukaan prisma segitiga!

bantu jawab ya qaqa

A=25cm, t=20cm, b=16cm, c=14cm , tentukan luas permukaan prisma segitiga!

Materi : Bangun Ruang dan Volume

Luas Permukaan Prisma Segitiga

Lp = a × t + ( a + t + s ) × tp

Lp = 16 × 14 + ( 16 + 14 + 25 ) × 20

Lp = 224 cm² + 55 cm × 20 cm

Lp = 224 cm² + 1.100 cm²

Lp = 1.324 cm²

Semoga bisa membantu

Lp = a × t + ( a + t + s ) × tp

Lp = 16 × 14 + ( 16 + 14 + 25 ) × 20

Lp = 224 cm^2 + 55 cm × 20 cm

Lp = 224 cm^2 + 1.100 cm^2

Lp = 1.324 cm^2
