GCSE Maths Practice: surface-area

Question 9 of 10

This question identifies 3D shapes that have flat faces.

‹ ›

\( \begin{array}{l}\text{Which 3D shapes have flat faces?}\end{array} \)

Select all correct options:

Focus on whether faces are flat and distinct. Ignore curved surfaces.

3D shapes can have flat or curved surfaces. Cubes, cuboids, and triangular prisms have flat faces, which allows their surface area to be calculated by summing the areas of each face. Spheres have a continuous curved surface and require a different formula. Understanding which shapes have flat faces is essential for correctly calculating surface area in practical applications like building design, packaging, and construction. Practice with various 3D shapes to strengthen spatial visualization and formula application skills.
