how do we find out the size of the markings of the inner square on the backboard
The backboard of a basketball goal is typically 1.80 meters by 1.05 meters in area. The diameter of the rim of the basket is 0.45 meters.
5,000,000,001 miles
Depends on the size of the board.
1.8x10^8 Nanometers
A NBA regulation backboard is 72" wide x 42" high
Each square is 1.5 in by 1.5 in
The outside measurement of the painted square on a regulation Size Basketball goal is 24"wide by 18" tall
So a size 7 basketball is a men's size basketball. A size 6 basketball is a woman's size basketball. That means a size 5 is for people who have smaller hands. That's how you compare sizes.
I'm assuming we are talking about the back board which has a standard size of 6 feet wide, 3 1/2 feet tall, and 1/2 inch thick.
A Size 7 basketball is usually 29.5 incheshttp://www.hrsinformer.com/2009/10/how-to-choose-a-basketball/
