Step-by-step explanation:

cut the diagram into two partsleft rectangle and right and add together.

left

V = l x w x h

= 5 x 6 x 12

=360

right

12 x 10 x 8

=960

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
