Applications of Integration: Volume Problem

Hello, I have a two problem in which I find difficult to understand.

Basically, it's the wording of the problems that's confusing the heck out of me. I have no problem with these types of problems in general so if a good Samaritan could kindly translate these problem into simpler terms for me I'd be extremely thankful. I can't help but think there's an easier way to write these.

1] Set up and evaluate the definite integral to find the volume of the solid between two planes perpendicular to the x-axis at x=0 and x=4. The cross sections perpendicular to the x-axis between these planes are equilateral triangles whose bases run from y=3sqrt(x) and y=-2x.

2] Setup and evaluate the definite integral to find the volume of the solid between the planes perpendicular to the x-axis at x=-1 and x=2. The cross sections perpendicular to the x-axis between these planes are squares whose bases run from y=x^2 and y=x+2.

Thanks in advance!
