Rasya mendapat tugas sekolah membuat kubus .Ukuran kubus nya hanya di ketahui volumenya.volume kubus pertama 5.832 cm^3 dan volume kubus ke dua 17.576 cm^3. berapa panjang kawat yang di perlukan untuk membuat kubus tersebut ???

Jawab:

Kubus pertama:

V = 5.832 –> r = 18
panjang kawat –> 18 * 12 = 216 cm

Kubus kedua:

V = 17.576 –> r = 26
panjang kawat –> 26 * 12 = 312 cm

Total panjang kawat –> 216 + 312 = 528 cm
