Total surface area of this triangular prism

of prism is 10 cm , can you help me to find the wide of prism

lculate surface area. (b) Calculate total capacitance presented by the cell membrane. (c) cell membrane has a resistance of 10 MΩ. Calculate τ (d) interior of the cell has an initial potential of Vi = 0 V, a potential of Vo = 100V is applied to the outside of the cell. Calculate how long it takes for the potential inside the cell to reach 50 V.
