Explanation: 1 bf = 12"x12"x1" OR 144 cubic inches OR 144 in3
The oak beam = 6"x6"x10' OR 6"x6"x120" OR 4320 in3
Therefore, to divide the beam up in to board feet (bf):
4320 in3 / 144in3 = 30 bf
More than 1. Describing the intensity of the beam will establish the number of photons per second striek a perpendicular surface of a given area.
A beam of light is made of photons, which are massless particles that carry electromagnetic energy. When a light source emits photons, they travel in waves at the speed of light, illuminating their surroundings.
how many feet of wire is in a slinky? 80 feet
the electrons are used to use to create an image apposed to the light because the beam of electrons has a smaller wavelength than light. This results in electron microscopes having a higher resolving power tham optical (light microscopes) Instead of lenses, the elctron microscopes use magnetic condensors to focus the beam. An image is generated by the electrons hitting a electrosensetive board connected to a computer. Each electron that lands on the board causes a voltage accross the board. The computer then generates an image from many voltages produced by the electrons
35000feet is how many kilometer?

Board feet can be determined when you have 3 dimensions for the board, but not with just two.
Depends on the size of the board.
170
450 feet
The board feet are approximately 8.004 cm`3
None. Board foot is a measure of volume not area.
High beam headlights can illuminate anywhere from 30 meters to 150 meters ahead of the car. This is 98 feet to 492 feet away.
