Volumes of 3D shapes (Edexcel GCSE Maths): Flashcards

$\frac{1}{3} \times \text{base area} \times \text{vertical height}$

$\frac{1}{3}\pi r^2h$

$\frac{4}{3}\pi r^3$

$\frac{4}{3}$ (only formula using this)

$\frac{1}{3} \times \text{base area} \times \text{vertical height}$

$\frac{1}{3}$

Leave in terms of $\pi$ to avoid rounding errors

Set volume expressions equal, then solve for unknown

$\frac{1}{3}$ of base area × vertical height

$\frac{1}{3}Ah$ ($A$=base area, $h$=height)
