Jawaban:
548 cm²
Penjelasan dengan langkah-langkah:
p = 18
l = 5
t = 8
L = 2 × (p.l + p.t +l.t)
L = 2 × [(18.5) + (18.8) + (5.8)]
L = 2 × (90 + 144 + 40)
L = 2 × 274 = 548 cm²
548 Cm
Pengerjaan:
Rumus Luas Permukaan Balok :
= 2 x ( p × l ) + ( p × t ) + ( l × t )
= 2 x ( 18 x 5 ) + ( 18 x 8 ) + ( 5 x 8 )
= 2 x ( 90 + 144 + 40 )
= 2 x 274
= 548 cm
Semoga Membantu ;)
