Prisms (Edexcel GCSE Maths): Flashcards

3D shape with same cross-section throughout its length

Area of cross-section × Length

Identify the cross-section

$\frac{1}{2}(a+b)h$ where $a,b$ are parallel sides

$\frac{1}{2} \times \text{base} \times \text{height}$

Add together areas of all faces

Two end faces (cross-sections) + all rectangular side faces

Cubic units (e.g., cm³, m³)

Square units (e.g., cm², m²)

Use reverse process to find missing dimension

Show all your working for partial marks

Forgetting to include hidden faces

Stacking identical cross-sections along length
