    Answer:

      yes, about 2.05 inches

    Step-by-step explanation:

    The Pythagorean theorem can be used to find the width of the TV.

      w^2 +h^2 = d^2

      w = √(d^2 -h^2)

      w = √(42^2 -18^2) = √1440 = 12√10

      w ≈ 37.95 . . . inches

    This dimension is less than 40 inches by a margin of …

      40 -37.95 = 2.05 . . . inches

    The TV will fit, with 2.05 inches of space remaining.
