34 tolong yahhhhhh....

Volume bak = p.l.t
1620 = 5x.4x.3x
1620 = 60x^3
x^3 = 1620/60
x^3 = 27
x = 3.
Panjang
= 5x = 5.3 = 15 cm.
Lebar = 4x= 4.3 = 12 cm
Tinggi = 3x= 3.3 = 9 cm.

MAPEL = MATEMATIKA
KELAS = 8
BAB = BANGUN RUANG

diketahui =
panjang = 5x
lebar = 4x
tinggi = 3x
V. balok = 1620cm³

ditanya = ukuran bak mandi tersebut??

V. balok = plt
1620 = 5x . 4x . 3x
1620 = 60x³
x³ = 1620/60
x³ = 27
x = ³√27
x = 3

panjang :
= 5x
= 5(3)
= 15cm

lebar :
= 4x
= 4(3)
= 12cm

tinggi :
= 3x
= 3(3)
= 9cm

semoga membantu
