January, February and March sheets built to one layout, rolled into a quarter summary by 3-D references: the finished IT153 Unit 8 workbook, set in a composite lawn care firm. Searches like "it 153 unit 8 assignment example", "it153 unit 8 sample" and "it153 unit 8 example" land here.
What a finished IT153 Unit 8 multi-sheet workbook looks like
Six tabs in a deliberate order: Contents, Rates, January, February, March and Q1 Summary. Rates lists hourly charges for mowing, pruning, snow clearing and walkway repair. Each month sheet has the same grid, crews A, B and C down rows 6 to 8 and the four service lines across columns B to E, holding hours worked, with a revenue block beneath that multiplies hours by the matching rate through a cross-sheet reference such as Rates!$B$4. Q1 Summary uses 3-D references, =SUM(January:March!B12) and its neighbors, so each cell totals the same position on all three months. A quarter chart of revenue by service line sits on the summary. Contents carries hyperlinks to every sheet with a line describing each, and the three month tabs share one color.
How a IT153 Unit 8 example is structured
Everything in the workbook depends on the month sheets being identical in layout, so the example treats that as its first rule: same rows, same columns, same labels, differing only in the hours typed. That consistency is what lets a 3-D reference work, because January:March!B12 means the same crew and service line on every sheet. Rates live in one place and are referenced from each month, so a rate change flows to all three months and the summary. Sheet order matters, since a 3-D range includes every sheet positioned between its first and last names; the Rates and Contents tabs sit outside that span on purpose. The summary shows quarter totals with a column of monthly averages beside them. The Contents tab doubles as documentation, explaining every cross-sheet and 3-D reference in plain sentences.
Contents and sheet order
A first tab with hyperlinks to each sheet and one line describing it. Rates and Contents sit before January, and Q1 Summary after March, so no 3-D range can accidentally include them.
Rates tab
Four hourly charges, one per service line, labeled and formatted as currency. Every revenue formula on the month sheets refers here with an absolute cross-sheet reference, so a new rate needs one edit.
Identical month sheets
Hours by crew and service line in B6:E8, a revenue block below and totals in fixed positions. The three sheets carry matching tab colors, the same title format and one grid layout.
Summary with 3-D references
Each summary cell sums one position across January to March. A monthly-average column uses AVERAGE over the same 3-D range, and a column chart shows revenue by service line for the quarter.
Plain-sentence documentation
The Contents tab explains what Rates!$B$4 and January:March!B12 each mean in ordinary words, including why moving a sheet outside the span would change every summary total.
Where marks go in IT153 Unit 8
Multi-sheet workbooks lose points when the sheets stop matching. A crew row inserted on February alone shifts every cell below it, so the 3-D summary adds a revenue figure from one month to a totals cell from another and reports a number that looks reasonable and is wrong. Summaries built by typing the three monthly totals and adding them fail the reference test the unit exists for. Rates copied onto each month sheet, rather than referenced from one tab, drift apart the first time one is updated. Sheets dragged into the wrong order, a notes tab landing between January and March, silently join the 3-D range. Default tab names like Sheet3 and unlabeled summary cells cost smaller amounts. The strongest files look almost repetitive, which is exactly what makes their cross-sheet formulas trustworthy.

IT153 Unit 8 questions, answered
What is a 3-D reference?
A reference that points at the same cell or range on several sheets at once, written with the first and last sheet names separated by a colon, such as January:March!B12. Wrapped in SUM or AVERAGE, it totals or averages that position across every sheet in between. It only works when the sheets share an identical layout.
Why did my summary total change when I added a new sheet?
A 3-D reference includes every sheet positioned between its first and last names, so a new sheet placed inside that span joins the calculation automatically. That is useful when adding April to a year-to-date range and a problem when a notes or chart sheet lands there by accident. Moving the sheet outside the span restores the original total.
Can I group sheets to format them all at once?
Yes, and many IT153 prompts expect grouped formatting because it keeps identical sheets identical. While sheets are grouped, anything typed or formatted on one applies to all of them, which is powerful and risky. Ungrouping before entering each month's own data avoids overwriting the other sheets. The title bar shows Group while grouping is active.
