    16 boards that are 5.7 inches wide each make a total of 91.20 inches.

    16

    x 5.7

    112

    +800

    91.2 inches

    Since the deck itself is 94.45 inches deep, we can subtract 91.2 from the number:

    94.45

    -91.20

    3.25 inches.

    Finally, we divide 3.25 by 15, since that's the amount of spaces we want and they have to be equal:

    3.25/15 =.21667

    We'll round that to two numbers, so we'll end up with. 22.

    Your final answer is. 22 inches wide for each space.
