If each keg of nails weighs 100 pounds and there are four kegs, the total weight would be calculated as follows:

 4 kegs x 100 pounds per keg = 400 pounds

Therefore, the total weight of four kegs of nails is 400 pounds.

If a cutting wheel cuts through an inch of glass in 2 minutes, the time taken to cut through 6 inches would be calculated by multiplying the time per inch by the number of inches:

6  inches x 2 minutes per inch} = 12 minutes

Therefore, it will take 12 minutes to cut through 6 inches of glass.

The ancient Egyptians used the stars, particularly the North Star, to align the sides of their pyramids with great precision. They observed the sky to determine true north and other cardinal directions. This astronomical method involved tracking the movement of stars across the night sky to establish a north-south line. They also employed other tools and methods, such as sighting rods and water-filled trenches, to ensure their constructions were accurately aligned. This attention to celestial objects and their use of rudimentary but effective tools allowed them to align the pyramids remarkably well with the cardinal points.

Geology is the study of the earth's origin, history, and structure. It focuses on understanding the processes that have shaped the earth over millions of years, including the formation of rocks, minerals, and landforms. Geologists study the earth's layers, such as the crust, mantle, and core, and investigate the forces that have caused earthquakes, volcanic eruptions, and the movement of tectonic plates. By examining rocks and fossils, geologists also uncover evidence of past climates, ancient life forms, and the changes that have occurred on the earth's surface over time.

A sundial is considered the oldest time-telling device because it uses the position of the sun to indicate the time. It consists of a flat plate with markings that indicate the hours, and a shadow-casting object called a gnomon. As the sun moves across the sky, the shadow cast by the gnomon moves along the markings, allowing people to determine the time of day. Sundials have been used for thousands of years and were widely used before the invention of mechanical clocks. They are still used today as decorative or educational objects.
