Luas permukaan balok = ​

Answer 1

P = 12

L = 5

T = 9

DIT :

LP !

JAWAB :

LP = 2( PL + PT + LT )

= 2( 12.5 ) + ( 12.9 ) + ( 5.9 )

= 2( 60 + 108 + 45 )

= 2(213)

= 426 SATUAN BALOK

Answer 2

Mapel : Matematika

Kelas : VII

Kode soal : 2

-Penyelesaian-

2(P × l + p × t + l × t)

2(12 × 5 + 12 × 9 + 5 × 9)

2(60 + 108 + 45)

2(168 + 45)

2(213)
