Penjelasan dengan langkah-langkah:
Lp = 2 ( pl + pt + lt )
Lp = 2 ( 14 × 8 ) + ( 14 × 6 ) + ( 8 × 6 ))
Lp = 2 ( 112 + 84 + 48 ))
Lp = 2 ( 196 + 48 ))
Lp = 2 ( 244 )
Lp = 488 Cm²
Panjang = 14 cm
Lebar = 8 cm
Tinggi = 6 cm
• Ditanya :
Luas permukaan balok ?
• Jawab :
Lp = 2(pl + lt + pt )
Lp = 2(14(8) + 8(6) + 14(6) )
Lp = 2(112 + 48 + 84)
Lp = 2 ( 160 + 84 )
Lp = 488 cm²
Keterangan :
p = panjang
l = lebar
t = tinggi
Lp = Luas permukaan
