#### Solution

If `veca vecb and vec c` are conterminus edges of parallelopiped then the volume of the parallelopiped =`[veca vecb vecc]`

where `veca=2hati+3hatj-4hatk`

`vecb= 5hati+7hatj+5hatk`

`vecc=4hati+5hatj-2hatk`

`therefore V=[veca vecb vecc]=[[2,3,-4],[5,7,5],[4,5,-2]]`

`=2(-14-25)-3(-10-20)-4(25-28)`

`=2(-39)-3(-30)-4(-3)`

`=-78+90+12`

`=24 cube" "Unit`
