GCSE Maths Practice: surface-area

Question 10 of 10

This question tests which 3D shapes can have surface area calculated by summing face areas.

‹

\( \begin{array}{l}\text{Which shapes can have their surface area calculated by adding the area of each face?}\end{array} \)

Select all correct options:

Identify shapes with flat, separate faces. Use appropriate formula for curved shapes.

Cubes, cuboids, and triangular prisms consist of flat faces. Their surface area is found by adding the areas of all faces. Spheres, having continuous curved surfaces, use a different formula (4πr²). Recognizing which shapes allow summing of faces is vital for solving practical surface area problems in design, packaging, and manufacturing. Practice with various 3D shapes to ensure correct identification and computation of surface area.
