1.sebuah bangun kubus volumenya 778.688 cm panjang rusuknya adalah.......cm a.82 b.86 c.92 d.102 2.diketahui volume balok 6.912 cm,lebarnya 16 cm,dan tingginya

Kelas 5 Matematika
Bab Kubus dan Balok

^ = pangkat

1] Kubus
Volume = 778.688
s^3 = 778.688
s = ^3√(778.688)
s = 92 cm

2] Balok
Volume = 6.912
p x l x t = 6.912
p x 16 x 18 = 6.912
p = 6.912/288
p = 24 cm

[tex]1)v = s \times s \times s \\ v = 778688cm {}^{3} \\ s = \sqrt[3]{778688} \\ s = 92cm \\ \\ 2)v = p \times l \times t \\ v = 6912cm {}^{3} \\ l = 16cm \\ t = 18cm \\ p = \frac{6912}{16 \times 18} \\ p = \frac{6912}{288} \\ p = 24cm[/tex]
