Penjelasan dengan langkah-langkah:
Lp = 2pl+2pt+2lt
2.620 = 2(25)(20) + 2(25)t + 2(20)t
2.620 = 1000+50t+40t
2620=1000+90t
1620=90t
t= 1620/90
tinggi = 18 cm
L.p = 2( p × l ) + 2( p × t ) + 2 ( l × t )
2620 = 2( 25 x 20 ) + 2( 25t ) + 2( 20t )
2620 = 1000 + 50t + 40t
1620 = 90t
Jadi Tinggi Balok Adalah 18 Cm

Jawaban
L.p = 2( p × l ) + 2( p × t ) + 2 ( l × t )
2620 = 2( 25 x 20 ) + 2( 25t ) + 2( 20t )
2620 = 1000 + 50t + 40t
1620 = 90t
t = 18 cm
Jadi Tinggi Balok Adalah 18 Cm
