Tolong dibantu ya......
Misal:
- p = 3x cm
- l = 2x cm
- t = x cm
[tex] \: [/tex]
Cari nilai x:
K = 4(p + l + t)
96 = 4(3x + 2x + x)
96/4 = 6x
24 = 6x
x = 24/6
x = 4
maka:
- p = 3x cm = 3(4) cm = 12 cm
- l = 2x cm = 2(4) cm = 8 cm
- t = x cm = 4 cm
.
V = p × l × t
V = 12 cm × 8 cm × 4 cm
V = 384 cm³

keliling = 4( p + l + t)
96 = 4(3x + 2x + x)
96 = 4(6x)
96 = 24x
x = 96/24
x = 4
