Question

Volume bangun di atas adalah... tolong pakai proses

Answer 1

P = 25 cm
l = 8 cm
t balok = 10 cm
t limas = 25 - 10 = 15 cm

L alas = p × l = 25 × 8 = 200 cm2

V balok = L alas × t balok
= 200 × 10 = 2.000 cm3

V prisma = 1/3 × L alas × t prisma
= 1/3 × 200 × 15
= 200 × 15/3
= 200 × 5 = 1.000 cm3

V total = V balok + V limas
= 2.000 + 1.000 = 3.000 cm3 (c)

maaf kalau salah
semoga membantu
