The volume of a right triangular prism A...

The volume of a right triangular prism ABC`A_(1)B_(1)C_(1)` is equal to 3 cubic unit. Then the co-ordinates of the vertex `A_(1)`,if the co-ordinates of the base vertices of the prism are A(1,0,1), B(2,0,0) and C(0,1,0), are

A

`(2,2,2)`

B

`(0,2,0)`

C

`(0,-2,2)`

D

`(0,-2,0)`

Text Solution

Verified by Experts

The correct Answer is:
A, D
a,d
Knowing the volume of the prism we find its altitude `H=(A A_(1))=` and designing the vertex `A_(1)(x_(1),y_(1),z_(1))` relate the co-ordinate of the vector `vec("AA")_(1)` perpendicular to `vec(AC)`]
