(ii) The cuboid has _________ pairs of identical plane surfaces.
(iii) All the surfaces of a cube are _________ to each other.
(iv) All the edges of a cube are _________.
(v) Opposite edges of a cuboid are _________.
(vi) A _________ has no vertex, and no edge.
2. Complete the following table by filling in the boxes:
3. Define the following:
(i) edge
(ii) vertex
4. Write ‘true’ or ‘false’ for each statement as the case may be:
(i) Every cuboid is a cube.
(ii) Every cube is a cuboid.
(iii) All faces of a cube are similar in shape and size.
