tolong jawab semunya ya terimakasih tolong jawab

1.p x l x t
2.12 cm
3.gak tau 
terimakasih 
semoga enjoy jawabannya

1) V = s × s × s
V = s³

2) V = s³
V = 12³
V = 1.728 cm³

3) panjang kerangka
= 12 × 6 dm
= 72 dm
= 720 cm

4) rusuk = panjang kerangka ÷ 12
= 300 cm ÷ 12
= 25 cm³
Volume = s³
= 25 × 25 × 25
= 15.625 cm³

5) LP = 6 × s²
96 cm² = 6 × s²
s² = 96 ÷ 6
s = √ 16
s = 4
Volume = s³
= 4 × 4 × 4
= 64 cm³

6) V = p × l × t
= 3 × 1,5 × 2
= 9 cm³

7) V = p × l × t
= 18 × 15 × 12
= 3.240 cm³
