    answer:

    Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

    answer:

    Tessie is 34 yrs old

    Rhio is 20 yrs old

    Step-by-step explanation:

    let x - age of Tessie

    y - age of Rhio

    x + y = 54 y = 54 - x --- eq. 1

    2y - x = 6 eq. 2

    2(54 - x) - x = 6

    108 - 2x - x = 6

    3x = 108 - 6

    3x = 102

    x = 34 --- age of Tessie

    y = 20 age of Rhio

    To check

    2y - x = 6

    2(20) - 34 = 6

    40 - 34 = 6
