    Answer:

    46 square inches.

    Step-by-step explanation:

    Given that:

    • The cover of the wallet is 3 inches by 5 inches
    • It has a thickness of 1 inch

    This is in the shape of a rectangular prism.

    To find out how much duct tape Shawn will need, we find the total surface area of the wallet.

    Total Surface Area of a rectangular prism =2(LB+LH+BH)

    L=5 in., B=3in., H=1 in.

    Therefore:

    Total Surface Area of a rectangular prism =2(5*3+5*1+3*1)

    =2(15+5+3)

    =2(23)

    =46 Square Inches

    The amount of duct tape needed will be 46 square inches.
