Higher November 2024 Paper 1 Q8
8 The diagram shows a solid triangular prism on a horizontal floor.

The face in contact with the floor is a rectangle of width 2 m.
The pressure on the floor due to the prism is 80 newtons/m2
The force exerted by the prism on the floor is 720 newtons.
Work out the length of the prism. (3)
| Answer | Mark | Mark scheme |
|---|---|---|
| 4.5 | P1 | for process to find the area, eg \(80 = \dfrac{720}{A}\) or (area =) \(\dfrac{720}{80}\ (= 9)\) or \(80 = \dfrac{720}{2x}\) or \(2x = \dfrac{720}{80}\) |
| P1 | for complete process to find the length, eg \(\text{``}9\text{''} \div 2\) or \(720 \div (2 \times 80)\) | |
| A1 | for 4.5 oe |
