6
To score a six in cricket, you have to hit the ball so that it crosses the boundary rope on the foul.
According to the Laws of Cricket, the boundary where a rope is used is the inside edge of that rope. A ball that lands directly on the rope will be a six, provided that it only landed on the rope, and didn't touch both the ground inside and the rope at the same time (this would be a four only); this is the ruling used in international games.
Its commonly called the "boundary rope" (even if the actual material is not made of rope!)
The white line painted around the oval to determine the field of play is called the boundary line.
The perimeter of the cricket pitch is known as the boundary, if a batsmen hits the ball over this perimeter (usually represented by a line or a rope) they have hit a boundary. If the ball travels over this line without hitting the floor it is a 6 and if it makes contact with the floor before hitting the line it is a 4. Both of these are known as boundarys.
In England and in most countries that play cricket, an over consists of six ball over.
Technically speaking there are none. Where baseball has 4 bases, cricket is played on a pitch with 2 ends, and the batsmen get a run when they both cross to the other end safely. If they hit the ball to the boundary rope, then its 4 runs. If they hit it over the rope (similar to a home run in Baseball), then it counts as 6 runs.
Over the years the bats have changed shaped, this was because they used to bowl under arm. And also instead of the boundary being the fence it is know the rope.
Though the shape and dimensions of a professional Cricket Ground have not been defined or fixed, but as per the law 19.1, ICC has defined the playing conditions; diameters and minimum and maximum size of the playing surface. As per the law the playing area should be a minimum of 150 yards from boundary to boundary. Square boundary should be minimum of 60 yards and straight boundary of 70 yards, subject to no boundary exceeding 90 yards. The distance should be measured from the centre of the pitch. A three yards gap is also required between the boundary rope and the surrounding facing. It also requires more than 20,000 square yards of grass.
Reflected but not inverted
4 runs! It crosses the rope with a bounce or role's.
