The long jump boards are the white lines that line the run way of the pit. These lines are certain lengths away from the edge of the pit. For outdoor the distances from the board to the pit are 4' 8' & 12' in indoor the distances away from the board are 5' & 10'
Runners run down a runway to a board 20 cm wide they must jump from without the planting foot crossing the plane of the board(forward) and land in a sand pit. From the forward edge of the board to the place nearest where the runner landed in the sand pit is the jump distance measured in meters. In the USA this measurement is in meters and/or feet.
Long jump is measured from the takeoff line to the closest landing point in the sand pit. The distance is measured in meters from the edge of the takeoff board where the athlete's foot leaves the ground to the mark left by the athlete's nearest body part.

just that: the sand pit.
A jump is measured from the foul line to the first spot where the athlete touched in the sand pit.

The long jump consists of four key elements: approach run, takeoff, flight, and landing. The athlete must generate speed during the approach run, execute a powerful takeoff from the takeoff board, maximize distance during the flight phase using proper technique, and land securely in the sand pit to complete the jump.
