Question

A cheese shop has some bulk cheese in blocks measuring 30 cm x 20 cm x 8 cm. How much paper is needed to cover the block of cheese

Answer 1

232cm

Explanation:

A cheese usually has the shape of a cuboid.

Characteristics of a Cuboid

1. A cuboid is a convex polyhedron
2. It has 12 edges
3. It has 8 faces
4. Its base shape is a rectangle
5. It has 6 faces

The amount of paper that would be needed to cover the block of cheese can be determined by calculating the perimeter of the block of cheese which is shaped as a cuboid

Perimeter of a cuboid = 4 x (length + breadth + height)

4 x (30 + 20 + 8) = 232cm
