|---|---|---|
| 13200 × 460 ÷ 3 | M1 | Or equivalent. |
| = 2024000 (cm3) | A1 | |
| = 2.024(m3) | B1 | Strict FT of a correct conversion of their volume to m3. |
Alternative method
| Scheme | Marks | Comments |
|---|---|---|
| Sight of 1.32 AND 4.6 | B1 | |
| 1.32×4.6÷3 | M1 | FT ‘their 1.32’ and ‘their 4.6’ from place value errors for M1A1. |
| = 2.024(m3) | A1 |
