Foundation June 2025 Paper 2 Q18
18 A cube has a volume of 512 cm3
Work out the surface area of the cube. (3)
| Answer | Mark | Mark scheme |
|---|---|---|
| 384 | P1 | for \(\sqrt[3]{512}\ (= 8)\) or \(512 \div 8\ (= 64)\) |
| P1 | for \(\text{``}8\text{''}^2 \times 6\) \(\text{``}\sqrt[3]{512}\text{''} \times \text{``}\sqrt[3]{512}\text{''} \times 6\) | |
| A1 | cao |
Additional guidance
A correct answer coming from an incorrect method, eg \(512 \div 4 = 128\) and \(128 \times 3 = 384\) will score no marks
