**(a).** The given function is f(s) = 6s^{2}. Put s = 3.75 m, we have, f(3.75) = 6 (3.75)^{2} = 6 × 3.75 × 3.75 f(3.75) = 84.4 m^{2}

- A cube has 6 faces.
- A cube has all its sides mutually equal; l = h = w.
- If ‘s’ is the length of the side of a cube, then the surface area of the cube = 6s
^{2}

**(b).** The given function is f(s) = 6s^{2}. Put s = 6.05 inch, we have, f(6.05) = 6(6.05)^{2} = 6 × 6.05 × 6.05 f(6.05) = 219.615 in^{2} **(c).** The given function is f(s) = 6s^{2}. Put s = 13.42 mm, we have, f(13.42) = 6(13.42)^{2} = 6 × 13.42 × 13.42 f(13.42) = 1077.36 mm^{2}
