Info a submarine is 294 feet below sea level A helicopter is flying directly over the submarine 1277 feet above sea level what is the distance from the helicopter to the submarine?

If we have 294 + 1277 here, it will equal 1571 feet. The reference is sea level, and the submarine is 294 feet below it. As the helicopter is at 1277, by adding 294 and 1277, we get the distance between the sub and the chopper, which is 1571 feet.

How much lumber will you need to build a 12x20 shed with 8ft walls and 12ft center ceilings?

To calculate the amount of lumber needed for the shed, you first need to determine the perimeter of the shed, which is 2(12+20) = 64 feet. Next, calculate the total wall area by multiplying the perimeter by the wall height: 64ft * 8ft = 512 square feet. To find the amount of lumber needed, divide the total wall area by the area covered by each piece of lumber. If you are using standard 8ft long 2x4 lumber, each piece covers 8sq.ft. Therefore, you will need 512sq.ft / 8sq.ft = 64 pieces of lumber for the walls.

If A Piece Of Lumber Is 17 Feet Long You Cut The Lumber Into Logs That Are 18 Inches Long How Many Inches Of Lumber Remain?

First, convert the length of the lumber from feet to inches: 17 feet is equal to 204 inches (17 feet x 12 inches/foot). Next, determine how many 18-inch logs can be cut from 204 inches: 204 inches ÷ 18 inches/log = 11 logs with a remainder. The total length used for 11 logs is 198 inches (11 logs x 18 inches), leaving a remainder of 6 inches of lumber. Therefore, 6 inches of lumber remain.

How many 2x4s are in a unit of lumber?

A standard unit of lumber, often referred to as a "lumber unit" or "board foot," typically contains 1,000 board feet. Since a 2x4 measures 1.5 inches by 3.5 inches and is usually 8 feet long, it equals 5.33 board feet per piece. Therefore, a unit of lumber contains approximately 187 pieces of 2x4s, assuming standard lengths and no waste.
