volume sebuah balok adalah 4.096 cm. jika perbandingan antara panjang, lebar, dan tinggi balok adalah 4:2:1, hitunglah ukuran masing - masing sisi balok tersebu

P = 4 × n = 4n

l = 2 × n = 2n

T = 1 × n = 1n


V = P × L × T

4.096 = 4n × 2n × 1n

4.096 = 8n

n = 4.096 ÷ 8

n = 512 (diakarkan pangkat 3)

n = 8 cm


jdi


P = 4n = 4 × n = 4 × 8 = 32 cm

L = 2n = 2 × n = 2 × 8 = 16 cm

T = 1n = 1 × n = 1 × 8 = 8 cm

V = p.l.t
4.096 = 4n × 2n × n
4.096 = 8n³
n³ = 4.096/8
n³ = 512
n = 8

panjang, lebar, tinggi balok sebenarnya:
p = 4n = 4(8) = 32 cm
l = 2n = 2(8) = 16 cm
t = n = 8 cm
