Foundation November 2024 Paper 1 Q14
14 Here is a cuboid of length 10 cm and width 4 cm.
The cuboid has a volume of 200 cm3
(a) Work out the height of the cuboid. (2)
Here is a different cuboid.
(b) Work out the total surface area of this cuboid. (3)
| Answer | Mark | Mark scheme |
|---|---|---|
| 5 | P1 | for a start of a method to find the height, eg \(10 \times 4\ (= 40)\) or \(200 \div 10\ (= 20)\) or \(200 \div 4\ (= 50)\) or for forming a correct equation \(10 \times 4 \times h = 200\) |

| Answer | Mark | Mark scheme |
|---|---|---|
| 126 | M1 | for a start to find the area of at least one face, eg \(6 \times 3\ (= 18)\) or \(5 \times 3\ (= 15)\) or \(6 \times 5\ (= 30)\) |
| M1 | for combining the area of at least three of the correct faces eg \(\text{``}18\text{''} + \text{``}15\text{''} + \text{``}30\text{''}\ (= 63)\) or \(2 \times \text{``}18\text{''} + \text{``}15\text{''}\) | |

Additional guidance
Do not award first M if multiplied by a third length (ie volume calculation)
May be part of a larger addition including incorrect areas.
Do not award if more than 6 areas added.
