T is a parallelepiped in which A,B,C and D are vertices of one face and the face just above it has corresponding vertices A’,B’,C’,D’,T is now compressed to S with face ABCD remaining same and shifted to A”,B”,C”,D”, in S. The volume of parallelepiped S is reduced to 90% of T. Prove that locus of is a plane.

A parallelepiped S has base points A ,B ,Ca n dD and upper face points A^(prime),B^(prime),C^(prime),a n dD ' . The parallelepiped is compressed by upper face A ' B ' C ' D ' to form a new parallepiped T having upper face points A prime prime,B prime prime,C prime prime and D prime prime . The volume of parallelepiped T is 90 percent of the volume of parallelepiped Sdot Prove that the locus of A" is a plane.

Draw a diagram to represent a cube.Label its vertices as A,B,C,D,E,F,G and H Now write the names of its faces and edges.

A, B,C and D are playing cards. A and C, and B and D are partners. D is to the right of C. The face of C is towards West. Find the direction that D is facing.

If the two diagonals of one its faces are 6 hat i+6 hat ka n d4 hat j+2 hat k and of the edges not containing the given diagonals is c=4 hat j-8 hat k , then the volume of a parallelepiped is a. 60 b. 80 c. 100 d. 120
