I would hazard a guess that 7 x 4 refers, precisely, to the measurements. That could hardly be meters, centimeters, or millimeters; it is probably the dimensions of the table in feet.
About 7 3/4 inches.

what it the average weight of a 7 foot slate pool table

About 7 3/4 inches.
As per the www.billiard-place.com, pool table lights should be hung 30" above the playing surface of the table. That way the light will not shine in your eyes and properly light up all the table.
1 1/2" by 7 1/4".
The smallest pool tables made that generally conform to regulation pool tables is the 6 foot table. This is often referred to as a junior size. Smaller sizes are generally toys, and larger sizes are in regular use, from 7 foot to 10 foot.
Because....4 x 7 = 28 !
In 8 ball pool there are 16 balls on the table, a cue ball, 8 ball, 7 solids and 7 stripes although they could be red and yellow etc. In 9 ball there are 10 balls on the table, cue ball, 1-7 solid, 8 ball and striped 9 ball.
In the US, a pool ball is 2 and 1/4 inches. If you wish to measure it for wear and out of round you need to purchase a special tool or use a micrometer. To be a legal ball it cannot be out of roound by more than 0.005 inches.
The pocket openings for pool tables are measured between opposing cushion noses where the direction changes into the pocket (from pointed lip to pointed lip). This is called mouth. Corner Pocket Mouth: between 4.5 [11.43 cm] and 4.625 inches [11.75 cm] Side Pocket Mouth: between 5 [12.7 cm] and 5.125 inches [13.0175 cm] *The mouth of the side pocket is traditionally ½ inch [1.27 cm] wider than the mouth of the corner pocket.
