Function definition: Volume of a pyramid Define a function CalculatePyramidVolume with inputs baseLength, baseWidth, and pyramidHeight. The function returns pyramidVolume, the volume of a pyramid with a rectangular base. Hint: Recall that a function declaration begins with function. Pay attention to the spelling and character case of variables. Ex: pyramidvalue and pyramidValue are different variables. Relevant geometry equation: pyramidVolume baseLength baseWidth pyramidHeight 1/3 Ex: CalculatePyramidvolume(1, 1, 1) returns ans 0.3333 Your Function Save C Reset MATLAB Documentation 1% Define a function calculatePyramidVolume % Function inputs: baseLength, basewidth, and pyramidHeight % Function output: pyramdvolume 4 function (Pyramidvolume)- (baseLength,basewidth,pyramidHeight) calculatepyramidvolume- baseLength basewidth"pyramidHeight 1/3 Function call in expression: Reduced pricing Write a single statement that assigns totalCost with the discounted cost of item 1 and item 2. Use the provided function DiscountedPrice to determine the discounted cost of each item: function saleItemCost DiscountedPrice(originalItemcost, discountedRate) % originalitemCost: Original cost of an item in dollars % discountedRate: Discount rate as a decimal value saleItemcost originalItemcost (1 - discountedRate); end Ex: If item 1 costs 10 and has a 0.5 discount rate, and the item 2 costs 20 and has a 0.4 discount rate, then assign totalCost with 17 (l.e. DiscountedPrice(10, 0.5)+DiscountedPrice(20, 0.4) is equal to 5 12).
