Verified answer

BIlangan Kubik

3.
V1 + V2 = 11.375
r1³ + r2³= 11.375
15² + r2³ = 11.375
r2³ =11.375 - 15³ = 11.375 - 3.375
r2³ = 8.000 = 20³
r2 = 20
panjang rusuk kedua = 20 cm

4.  7 pangkat 3 = 7³ = 7 x 7 x 7 = 343

5. bilangan kubik antara 200 sd 700
5³ = 125
6³ = 216
7³ = 343
8³ = 512
9³ = 729
bilangan kubik = 216, 343, 512
