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
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]".
A sphere
The amount of space inside a three-dimensional figure is its volume. Volume measures how much substance can fit within the boundaries of the shape and is typically expressed in cubic units. Different geometric shapes have specific formulas for calculating their volume, such as length × width × height for a rectangular prism or (4/3)πr³ for a sphere.

Volume if it's a 3D figure and area if it's a 2D figure
A sphere has the lowest surface area to volume ratio of all geometric shapes. This is because the sphere is able to enclose the largest volume with the smallest surface area due to its symmetrical shape.

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.
Difficulty in calculating volume: Irregular solids have complex shapes that do not have simple geometric formulas to calculate their volume. Inaccurate measurements: Due to their irregular shape, measuring the dimensions of irregular solids can be challenging and may lead to inaccurate calculations. Limited surface area formulas: Unlike regular solids, irregular solids do not have standard surface area formulas, making it harder to calculate their surface area.
