How do you find the volume of a prism if the width is x, height is #2x-1# and the length if #3x+4#?
I'm assuming here that you mean a square prism:
For every prism, the volume is given by the formula:
In this case, the cross section is a rectangle. The area of a rectangle can be calculated by doing
So, the formula for these kind of prisms becomes:
Entering your values into the formula:
You can bring the
And now, you can use FOIL.
This is the volume.
I hope this is what you meant, and that it helped.
