GCSE Maths Practice: volume

Question 5 of 10

This question explores how volume changes when all dimensions of a solid are doubled.

‹ ›

\( \begin{array}{l}\text{What happens to the volume if all dimensions are doubled?}\end{array} \)

Choose one option:

When all dimensions double, cube the scaling factor to find new volume.

Volume depends on three dimensions: length, width, and height. If each dimension is doubled, multiply each by 2. The new volume is 2×2×2 = 8 times the original volume. For example, a cube of side 3 cm has volume 27 cm^3; doubling the side to 6 cm gives 6×6×6 = 216 cm^3, which is 8 times larger. Understanding this helps in scaling objects in real life, such as containers, boxes, or 3D printed objects. Always consider that volume grows exponentially with changes in dimensions. Practice with different solids and doubling scenarios to internalise this principle.
