LP = 2( PL + PT + LT )
= 2( 2.12 ) + ( 2.3 ) + ( 12.3 )
= 2(24 + 6 + 36)
= 2(66)
= 132 CM²
Jawaban:
132 cm³.
Diketahui :
panjang (p) = 2 cm
lebar (l) = 12 cm
tinggi (t) = 3 cm
Ditanya : Luas permukaan balok?
Jawab :
Lp = 2 × (p × l) + (p × t) + (l × t)
Lp = 2 × (2 × 12) + (2 × 3) + (12 × 3)
Lp = 2 × (24) + (6) + (36)
Lp = 2 × 66
Lp = 132 cm³
Semoga membantu!!!
