This introduction covers Stacking Slices within Volume of Cuboids & Prisms for GCSE Mathematics. Revise Volume of Cuboids & Prisms in Geometry & Measures for GCSE Mathematics with 20 exam-style questions and 12 flashcards. This topic shows up very often in GCSE exams, so students should be able to explain it clearly, not just recognise the term. It is section 1 of 9 in this topic. Use this introduction to connect the idea to the wider topic before moving on to questions and flashcards.
Stacking Slices
Imagine slicing a Toblerone lengthwise - every slice has the exact same triangular shape! A prism is any 3D shape where you can slice it and get identical cross-sections all the way through. To find its volume, just find the area of one slice and multiply by how many slices (the length).
Practice questions for Volume of Cuboids & Prisms
Which formula correctly calculates the volume of a cuboid?
A cuboid measures 10 cm × 10 cm × 10 cm. A cylinder has a diameter of 10 cm and a height of 10 cm. Which shape has the greater volume? Explain your reasoning without calculating exact volumes.
Quick recall flashcards
Volume of a cuboid
V = length × width × height
V = l × w × h
Units: cm³, m³, mm³
Volume of any prism
V = Cross-sectional Area × Length
Works for ALL prisms: cuboid, triangular prism, cylinder, L-shaped prism, etc.
