Q.

Diketahui sebuah balok memiliki panjang, lebar, dan tinggi berturut turut 10 cm, 5 cm, dan 3 cm. Tentukan volume dan luas permukaan nya !​

Answer 1

V = P × L × T

V = 10 × 5 × 3

V = 50 × 3

V = 150 cm³

LP = 2 × (P(L) + P(T) + L(T))

LP = 2 × (10(5) + 10(3) + 5(3))

LP = 2 × (50 + 30 + 15)

LP = 2 × (80 + 15)

LP = 2 × 95

LP = 190 cm²

koreksi

Answer 2

SOAL 1

___________________________________________

V Balok = P × L × T

___________________________________________

V Balok = 10 × 5 × 3

V Balok = 10 × 15

V Balok = 150 cm³

___________________________________________

Lp Balok = 2 × [PL + PT + LT]

___________________________________________

Lp Balok = 2 × [(10 × 5) + (10 × 3) + (5 × 3)]

Lp Balok = 2 × [50 + 30 + 15]

Lp Balok = 2 × [50 + 45]

Lp Balok = 2 × 95

Lp Balok = 190 cm²
