Higher June 2023 Paper 1 Q3
3 A cube has a total surface area of 150 cm2
Work out the volume of the cube. (4)
| Answer | Mark | Mark scheme |
|---|---|---|
| 125 | P1 | for process to find area of one face, eg \(150 \div 6\ (= 25)\) or \(6x^2 = 150\) |
| P1 | for process to find side length, eg \(\sqrt{\text{``}25\text{''}}\ (= 5)\) | |
| P1 | for a complete process to find volume, eg \(\text{``}5\text{''} \times \text{``}5\text{''} \times \text{``}5\text{''}\) or \(\text{``}25\text{''} \times \text{``}5\text{''}\) | |
| A1 | cao |
