Let's me answer your question :)
===========================

Jawaban :
Luas permukaan balok
= 2 × (p × l) + (p × t) + (l × t)
= 2 × (20 × 16) + (20 × 5) + (16 × 5)
= 2 × (320 + 100 + 80)
= 2 × 500
= 1000 cm^2

Semoga Membantu

Lp=2×(p×l)+(p×t)+(l×t)
=2×(20×16)+(20×5)+(16×5)
=2×320+100+80
=2×500
=1000
