Using the constants in cells A2:A9, create formulae for cells A12:A15 (surrounded by a dark line) to compute the corresponding "derived" physical constants indicated in cells B12:B15 Then create formulae for cells D18:D23 to compute product prices based on the corresponding input values in A18:A23 and the units in B18:B23. You can use some constants from A2:A9 in your formulae, if needed. Write formulae only; do not write actual numerical results. For example, if I type any number for grams of Spike Nails into cell A18, then the cost in dollars for that quantity of Spike Nails should automatically appear in cell D18. You write the formula to go in D18 in terms of input cell A18 and the cell addresses of the required conversion constants. Use only cell addresses in your formulae; do not use actual numbers TA Physical Units 101 ???
