1. √125 = 5
luas = 5.5 = 25
2. 214 = 2.6.7 + 2.7.l + 2.6.l
214 = 84 + 14l+12l
130 = 26l
5=l
a. lebar = 5 cm
b. v.= 5.6.7 = 210 cm3

1. Sisi = 3√Volume = 3√125 = 5
2. a. 4(13 + x) = 214
52 + 4x = 214
4x = 162
x = 40.5
b. 6.7.40,5 = 42 . 40,5= 1701
tpi pr q luas sisi kok :/
kalau luas alas baru sisi x sisi = 5x5 = 25 :)
ok fix :)
mohon pointnya :3
