ada yang tau caranya n0 1 , 2 , 3 ? please bantu ya kakak :)

1) V1 = p × l × t
= 8 × 8 × 4
= 256 cm³
V2 = p × l × t
= 25 × 8 × 8
= 1600 cm³
Vttl = 256 + 1600 = 1856 cm³

2) V1 = r³
= 6 × 6 × 6
= 216 cm³
V2 = p × l × t
= 20 × 6 × 8
= 960 cm³
Vttl = 216 + 960 = 1176 cm³

3) V1 = p × l × t
= 15 × 5 × 6
= 450 cm³
V2 = r³
= 5 × 5 × 5
= 125 cm³
Vttl = 450 + 125 = 575 cm³
