    Solutions
    Converting the equation into normal one and applying BODMAS:
    14 x 12 – 16 ÷ 18
    14 + 12 × 16 – 18

    The areas of three adjacent faces of a cuboid are 18 cm2, 20 cm2 and 40 cm2. What is the volume (in cm3) of the cuboid?
    Solutions

    Area of three adjacent faces of a cuboid are 18 cm2, 20 cm2 and 40 cm2.

    Then let the length be denoted by l , breadth by b and height be h

    Then l × b = 18

    b × h = 20

    h × l = 40

    then multiplying the above equations :

    (lbh)2 = 18 × 20 × 40

    = 144 × 100

    lbh = 12 × 10

    volume = lbh = 120 cm3
