    Step-by-step explanation:

    substitute the given values for s and h into the formula

    SA = (2 * 2²) + (4 * 2 * 4) = 8 + 32 = 40

    Step-by-step explanation:

    Given that the surface area for a rectangular prism with a square base is SA=2s2+4sh.

    Where the values of the variables in the equation which are s and h are known, the area can be computed by the substitution of the known variables into the equation.

    Hence where s = 2 and h = 4

    SA = 2 (2) ² + 4 (2) (4)

    = 8 + 32

    = 40 units²
