volume balok = 116 cm² x 8 cm x 6 cm = 5568 cm²

L = 2 x ( p x l + p x t + l x t ) 116 = 2 x ( p x 8 + p x 6 + 8 x 6 ) 116/2 = 8 p + 6 p + 48 58 = 14 p + 48 58 - 48 = 14 p 10 = 14 p p = 10/14 = 5/7 cm maka volume = p x l x t = 5/7 x 8 x 6 = 34,2857 cm³
116 = 2 x ( p x 8 + p x 6 + 8 x 6 )
116/2 = 8 p + 6 p + 48
58 = 14 p + 48
58 - 48 = 14 p
10 = 14 p
p = 10/14
= 5/7 cm
maka volume =
p x l x t = 5/7 x 8 x 6 = 34,2857 cm³
