Roughly 12 square yards.
None because it's a hole but 6 cubic yards of dirt will fill it up.
You are mixing volume (square yard) and area (length x width). How deep do you want the dirt? One foot deep you need about 80 square yards of dirt.
You also need to specify the average depth.(And by "yards" we assume you mean cubic yards).
6 cubic yards of dirt will cover 70 sq ft ... 2 ft 3 3/4 inches deep
400 yards of dirt would be a pile that is 1 yard wide, 1 yard tall, and 400 yards long. This would equate to roughly 1,200 cubic yards of dirt.
There may be very little or even none . Topsoil and "dirt" are different substances
Roughly 12 square yards.
Yes you can all you need two do is separate the seat to make two seats
To calculate the volume of dirt needed to fill the area, you would need to know the depth of the area in yards. If the depth is 3 yards, then you would need 1800 yards of dirt (600 cubic yards ÷ 3 yards). If the depth is 1 yard, then you would need 600 yards of dirt.

There is about 2800lbs in 2 yards of top soil.

It all depends on how big the truck is. For example a dump truck having two rear axles is rated and usually can transport 18 yards of dirt. 1/2-3/4 and 1 ton are rated for just that 1/2-3/4 and 1 ton.
You will need approximately 1 cubic yard of dirt for a trench that is 1 foot wide, 36 feet long, and 3 inches deep.
14 cubic feet = 0.518 cubic yards
