Penjelasan dengan langkah-langkah:

lp balok

lp = 2 × ( pl + pt + lt )

lp = 2 × (( 12 × 8 ) + ( 12 × 8 ) + ( 8 × 8 ))

lp = 2 × ( 96 + ( 12 × 8 ) + ( 8 × 8 ))

lp = 2 × ( 96 + 96 + ( 8 × 8 ))

lp = 2 × ( 96 + 96 + 64 )

lp = 2 × ( 192 + 64 )

lp = 2 × 256

lp = 512 cm^3

——————————-

lp kubus

lp = 6 × s × s

lp = 6 × 16 × 16

lp = 6 × 256

lp = 1.536 cm^3

——————————-

lp gabungan balok dan kubus

lp balok + lp kubus

= 512 cm + 1.536 cm

= 2.048 cm^3

——————————-

• Jadi lp gabungan tersebut adalah 2.048 cm^3
