Dita = luas permukaan balok?
jawab=
luas permukaan=2×(p×l)+(p×t)+(l×t)
=2×(6×3)+(6×4)+(3×4)
=2×18 + 24 + 12
=2× 54
=108 cm²
2.Diket=P:7 cm
=l:2 cm
=t:3 cm
=2×(7×2)+(7×3)+(2×3)
=2× 14. + 21. + 6
=2×41
=82 cm²
3.diket=p:8 cm
=l: 4cm
=t:5 cm
=2×(8×4)+(8×5)+(4×5)
=2 × 32 + 40 + 20
=2×92
=184 cm²
4. diket=p:8 cm
=l:7 cm
=t:2 cm
=2×(8×7)+(8×2)+(7×2)
=2×56. + 16 + 14
=2× 86
=172 cm²
5.diket=p:15cm
=l:8 cm
=t:6 cm
=2×(15×8)+(15×6)+(8×6)
=2× 150 +90 + 48
=2× 288
=576 cm²
