Most drop towers require child riders to exceed a minimum height; limits vary widely depending upon the nature of the tower, with a 30-foot (9 m) tower for smaller children from 37 inches (95 cm) tall, and a 115-foot (35 m) tower having a 51-inch (130 cm) restriction.
How many sheet of copy paper equal an inch? Using good quality 24 pound paper, a one inch thick stack is about 215 sheets. Using the more common 20 pound paper - popular in schools - one inch is about 250 sheets. Edit
It is still possible to find a so-called âshort reamâ of only 480 sheets, however. Short reams are more common with fine or unique papers, but they do crop up in the realm of office supplies as well. Consumers should check for a label that will indicate whether or not a package of paper is a short ream.
