    A.

    45 cm²

    B.

    75 cm²

    C.

    47 cm²

    D.

    94 cm²

    Correct option is D

    Given:
    The areas of three adjacent faces of a cuboid are 5cm2,15cm2,27cm2 5cm^2 , 15cm^2 , 27cm^2​​
    Formula Used:
    Total surface area of cuboid = 2 (L×B+B×H+L×H)
    Where L,B and H are length, breadth and height respectively.
    Volume of cuboid =LBH
    Solution:
    In cuboid the adjacent faces area is given by: L×B, B×H, L×H
    Where,
    L×B=5cm2cm^2  ​
    B×H=15cm2cm^2​​
    L×H=27cm2 cm^2​​
    Total surface area of cuboid = 2 (L×B+B×H+L×H)
    = 2(5+15+27)
    =94cm2cm^2​​
