Supercapacitors, with capacitances of $1\mathrm{.}00F$ or more, are made with plates that have a spongelike structure with a very large surface area. Determine the surface area of a supercapacitor that has a capacitance of $1\mathrm{.}49F$ and an effective separation between the plates of $d=1\mathrm{.}77mm.$
