Answer 1

panjang balok = Lp - (2×3×2) : (2×3 + 2×2)

= (72 - 12) : (6+4)

= 60 : 10

= 6m

maaf klo slh :(

Answer 2

Rumus panjang balok : v ÷ (l × t)

Luas permukaan : 2 × ( p × l + p × t + l × t)

72 = 2 × ( p × 3 + p × 2 + 3 × 2)

72 = 2 × ( 3p + 2p + 6)

72 = 2 × ( 5p + 6)

72 = 10p + 12

72 - 12 = 60p

10p = 60

P = 60 ÷ 10

P = 6
