Answer 1

Verified answer

Kelas 8 Matematika
Bab Bangun Ruang

Volume = 192
3a . 4a . 2a = 192
24a³ = 192
a³ = 192/24
a = ∛8
a = 2

Panjang seluruh rusuk
= 4 . (p + l + t)
= 4 . (3a + 4a + 2a)
= 4 . 9 . 2
= 72 cm

Answer 2

Verified answer

Balok

Rasio :
p : t : l = 3 : 4 : 2

Volume balok = 192 cm³
p × l × t = 192
3x × 2x × 4x = 192
24x³ = 192
x³ = 192/24
x³ = 8 = 2³
x = 2

Panjang seluruh rusuk balok
= 4(p + l + t)
= 4 (3x + 2x + 4x)
= 4 . 9x
= 4 . 9 . 2
= 72 cm
