10.For the cuboid shown in Fig. 16.3,
(i)What is the base of this cuboid?
(ii)What are the lateral faces of this cuboid?
(iii)Name one pair of opposite faces. How many pairs of opposite faces are there? Name them.
(iv)Name all the faces of this cuboid which have X as a vertex. Also, name those which have VW as a side
(v)Name the edges of this cuboid which meet at the vertex P. Also, name those faces which meet at thisvertex.
(i)The base of this cuboid is UVWX
(ii)The lateral faces of this cuboid are UXSP, QVWR, SXWR and UVQP
(iii)One pair of opposite faces among the lateral faces of the base are PQVU and SXWR or UXSP and QVWR.We know that a cuboid has two pairs of opposite faces among the lateral faces of the base.
(iv)The faces of this cuboid which have vertex as X are UVWX, UXSP and SXWR.
We know that the faces having VW as a side are UVWX and QVWR
(v)The edges of this cuboid meeting at the vertex P are UP, PQ and PS.
We know that the faces which meet at this vertex P are PQRS, UPSX and PQVU
