Green oak has a density of 60 pounds per cubic foot. A block of this wood is 1 foot long, 2 feet wide and 3 feet deep. Create a spreadsheet which calculates how much the block weighs. Your spreadsheet should use the following techniques: 1) Short equations rather than one long equation 2) Separate inputs, calculations and outputs 3) Use cells which contain the values of the input parameters such as Width, rather than hardcoding the number 2 into a...
