kerjakan soal-soal berikut ini

1. La × T = ( a × t ÷ 2 ) × T = ( 18 × 24 ÷ 2 ) × 26 = 5616 dm3

2. La × T = ( a × t ÷ 2 ) × T = ( 24 × 10 ÷ 2 ) × 30 = 3600 dm3

3. La × T = ( a × t ÷ 2 ) × T = ( 15 × 36 ÷ 2 ) × 45 = 12150 cm3

4. La × T = ( a × t ÷ 2 ) × T = ( 16 × 12 ÷ 2 ) × 20 = 1920 dm3

5. La × T = ( a × t ÷ 2 ) × T = ( 20 × 15 ÷ 2 ) × 38 = 5700 cm3

6. diubah ke dm dulu semua
1,2 m = 1,2 × 10 = 12 dm
0,9 m = 0,9 × 10 = 9 dm
V = La × T = ( a × t ÷ 2 ) × T = ( 12 × 9 ÷ 2 ) × 18 = 972 dm3
