First, you need to know the volume of a cuboid which is nothing but Length, Breadth and Height multiplied.
So, you'll have to multiply all of the values.
Volume of a cuboid = $$l \times b \times h$$

anonymous · Answer

Now substitute : 
l = 5x - 4
b = x + 3
h = 2x - 1
Can you do it now?

i got 7x-1

anonymous · Answer

but thats not one of the choices

anonymous · Answer

No, shouldn't you be getting it in the variables in cubes?

Did you get how to do it yet? :?
First multiply 2 equations and then multiply their result with the third.
