If the volume of the parallelopiped with a, b and c as coterminous edges is 40 cubic units, then the volume of the parallelopiped having `b+c, c+a and a+b` as coterminous edges in cubic units is
A. 80
B. 120
C. 160
D. 40
A. 80
B. 120
C. 160
D. 40
Correct Answer – A
Given , volume of parallelopied `[abc]=40`
`therefore` Volume of parallelopiped `=[b+c c+a a +b]=2[abc]`
`2xx40=80` cu units. .
