The formulae will contain variables representing measure of the figure: the lengths of sides, vertical distance between sides or a point and a side, angles and so on. Find their values for the figure - by measurement, if necessary - and substitute ino the formula. Evaluate [work out the value of] the formula.
A pentagon is a two-dimensional geometric figure and therefore has area but not volume. To have volume, a geometric figure must have height or thickness as well as its plane dimensions.
It is its volume which is measured in cubic units
A sphere
That depends on the figure whose surface area and volume you're finding. You could try a Google search for "volume of [figure name]" or "surface area of [figure name]".
No solid figure has a surface area equal to its volume. That would not be possible as the units of measure are different.

Volume if it's a 3D figure and area if it's a 2D figure

If the cell has a simple geometric shape, there are formulae that can be used. Otherwise you need to measure the surface area and the volume.
Formula is a geometry term. Formulas are used to measure area and volume.
