nope

I don't think we can blow up the image.

To clarify, I'll re-write the question:

A contractor is to construct a tank using the information shown below, the number of pounds of steel that will be required is __________. Select the closest answer.

a) Less than 1,000 lbs.

b) 1,001 to 1,500 lbs.

c) 1,501 to 2,000 lbs.

d) over 2,000 lbs.

The image is pretty big, so I won't re-write that part.

Easy.

Just take the volume of the metal x the specific garvity. (Matweb will give you this)

You know the thickness, so just figure the volume from the dimensions provided.

If you already know the answer, I don't understand your dilemma.

Let's say I HOPE I don't understand your dilemma.

Maybe you should consider becoming a plumber. They only need to know three things.

1. smell goes up.

2. s%it goes down.

3. payday is on Friday.

2.5. Don't chew on your fingernails.

I think you have your ducts and your tanks confused....
