2)
Volume kubus = s^3
125 = s^3
s = ∛125
s = 5 cm
Luas permukaan = 6 s^2
= 6 x 5^2
= 150 cm2
3)
√48
= √16 x 3 ---> keluarkan 16 nya sehingga menjadi 4
= 4√3 cm
diagonal ruang = s√3
4√3 = s√3
s = 4 cm
volume = s^3
volume = 4^3
volume = 64 cm3
4) saya kurang tau
5) prisma
6)
Luas permukaan = 6 s^2
= 6 x 7^2
= 294 cm2
7)
Luas permukaan = 6 s^2
1.350 = 6 s^2
1.350 / 6 = s^2
s^2 = 225
s = 15 cm
diagonal ruang = s√3
diagonal ruang = 15√3 cm
