a) Differentiate between actual parameter and formal parameter. (2 marks) b) Write the function definition for each of the following problems: i) function cuboidVolume () that receives the length, width and height of a cuboid through its parameter. This function then calculates and return the volume using the formula: volume \( = \) length \( x \) width \( \times \) height (3 marks) ii) function sphereVolume () that receives the radius of a sphere through its parameter. This function then calculates and return the volume using the formula: \[ \text { volume }=\frac{4}{3} \pi r^{3} \]
