Hi there, pretty stuck on the following question from my exam revision:

Find the volume of the following parallelepiped, one of whose vertices is the origin, and with the edges linking the origin to the points (co-ordinates in Metres) (1) (1) (7)

(2) (0) (2)

(2) (3) (-1)

And also this, i think it is included:

Find the point of intersection of the following line and plane:

- The PLane passes through the points (3,3,4), (3,1,2) and (1,0,0)

- The line passes through the points (3,5,8) and (7,13,22)

THanks
