You have provided the length and width of the boards but only the width (height) of whatever you wish to board. there is no information on its length and consequently, the question cannot be answered.
There are 3 feet in a yard and 12 inches in a foot. Convert all boards to the smallest unit (inches) 2 ft 10 inches = 34 inches 1 yard 1 foot and 9 inches = 57 inches 34 +57 = 91 inches, ( or 7 feet 7 inches), (or 2 yards 19 inches), ( or 2 yards 1 foot 7 inches)
Convert inches to feet6 inches = 1/2 feetso it is a 16 x 0.5 foot board. Thus, the area of a board is16*0.5 = 8 feet squared.The number of 8 feet squared boards needed to cover 800 squared feet is800 squared feet/8 squared feet = 100
Assuming the two end pieces will also be 10 inches and the cuts do not take up any space, the board must be 130 inches long. But it could be only 122 inches if the first and last cuts are only 1 inch from the ends, but still 10 inches from the adjacent cuts. Or it could be any longer length if either or both of the ends is more than 10 inches.
Illustration boards come in a range of sizes.
No they are differant units of measurement. Board feet, is actually a measurement of volume. 1 board foot is the volume of a board 12" wide by 1" thick by 1 foot long. So to calculate board foot you would also need to know the thickness. Whereas linear feet is a measurement of length, equal to 12 inches, in this case. You can also have linear inches, yards, furlongs, etc.
There are 3 feet in a yard and 12 inches in a foot. Convert all boards to the smallest unit (inches) 2 ft 10 inches = 34 inches 1 yard 1 foot and 9 inches = 57 inches 34 +57 = 91 inches, ( or 7 feet 7 inches), (or 2 yards 19 inches), ( or 2 yards 1 foot 7 inches)
10m 7.5m and 5m hard boards and 1m and 2.5m spring boards.
Measure them.
FOUR
To obtain the board measure multiply the length in feet to be covered by the width in feet. If the boards are over one inch thick multiply this by the thickness in inches. Thus assuming the boards are 1 inch thick or less the board measure is 4 x 8 = 32 feet board measure (B.M.)
For platforms there are no boards this is just the platform, compared to spring board which is a flexible board that you do a hurdle off of to get maximum height. on a platform you get as much height as you can jump
Assuming that the boards are 2 inch x 14 inch then: Total width is 14x12 inches. Since the boards are 14 in wide the total required is 14. To calculate the board measure (which you will need for ordering purposes, multiply length in ft. by width in ft. of the board. Then multiply this product by the thickness in inches. Assuming the length is 20 ft then the board measure is 20ft x 14ft x 2in = 560 ft. B. M. Worked examples are at the accompanying web link.
You can divide the number of inches by 12, (the number of inches in a foot) to come up with a board length measurement.
2.5 inches
The plural of board is boards. As in "we looked at the drawing boards".
Length? Timber boards that are very long are hard to come by. You can buy manufactured board of great length. Manufactured board is supposed to be stronger, too.
A concert ukulele has a fret board that has a scale length of 15 inches and an overall length of about 23 inches.
