    Answer:

    2004 cm²

    Step-by-step explanation:

    To solve this problem, you just need to plug your values into the rectangular prism formula: A=2(wl+hl+hw)

    Assuming that the length is 21 cm, the width is 18 cm, and the height is 16 cm, your problem would look like this:

    A=2((18×21)+(16×21)+(16×18))=2(378+336+288)=2×1002=2004 cm²
