    The base of a rectangular prism (b) = 41 in.

    Step-by-step explanation:

    Given,

    The height of a rectangular prism (h) = 3 in and

    The perimeter of a rectangular prism = 88 in

    To find, the base of a rectangular prism (b) = ?

    We know that,

    The perimeter of a rectangular prism = 2l + 2b or 2b + 2h or 2h + 2l

    ∴ 2b + 2 (3) = 88

    ⇒ 2b = 88 - 6

    ⇒ 2b = 82

    ⇒ b = 41 in

    Thus, the base of a rectangular prism (b) = 41 in.
