Jawaban:
Rumus Luas permukaan balok
= 2( ( p × l ) + ( p × t ) + ( l× t) )
Penyelesaian:
Lp balok = 2 × ( ( p × l ) + ( p × t ) + ( l× t) )
1824 = 2× ( ( 36 × 12 ) + ( 36 ×t ) + ( 12 × t ) )
1824 = 2 × ( 432 + 36t + 12t )
1824 = 2 × ( 432 + 48 t )
1824 : 2 = 432 + 48t
912 = 432 + 48t
912 - 432 = 48 t
480 = 48 t
t = 480 / 48
t = 10
Semoga membantu,
