4. Volume of a Rectangular Pyramid is given below. (25%) V = (1/3)lwh ** ********* *** Write a bash script to Read the values for I, w and h and then calculate and print the volume of the pyramid. Here is an example run: written by: Your Name Enter the length of the rectangular base : 9.0 Enter the width of the rectangular base : 4.5 Enter the height : 10 Volume of the Rectangular Pyramid 135.000 cubic units. Important: For full credit, this calculation MUST work for floating point numbers also and NOT just for discrete (whole) numbers. [Look at Bash Practice Questions 02 on blackboard where it teaches you how to use the bc calculator for floating point numbers or look at the examples in page 57 of the class note) (YOU MUST INCLUDE THE SCRIPT FILE (.sh file) IN THE ZIP)
