Tolong dijawab ya pake cara dan bener semuaasal? report!!​

Penjelasan dengan langkah-langkah:

1.

=V¹ = P × L × T

=21 × 9 × 5

=945 cm³

=V² = P × L × T

=9 × 9 × 4

=324 cm³

=V.keseluruhan=V¹ + V²

=945 + 324

=1269 cm³

2.

=V¹ = P × L × T

=16 × 8 × 5

=640 cm³

=V² = P × L × T

=8 × 8 × 8

=512 cm³

=V.keseluruhan=V¹ + V²

=1269 + 512

=1781 cm²

3.

=V¹ = P × L × T

=10 × 5 × 8

=400 cm³

=V² = P x L x T

=5 × 5 × 13

=325 cm³

=V.keseluruhan=V¹ + V²

=400 + 325

=725 cm³
