What’s on the Volume poster
The rule, 4 worked examples, and the mistake everyone makes.
- Volume is the number of unit cubes that fit inside a solid. For any prism it is the b…
- V = l × w × h · V = B × h
- Box 4 × 3 × 2 = 24 cubic units
- Cube of side 5 = 125 units³
- Base area 20, height 6 = 120 units³
- Two boxes joined = add the volumes
- Common mistake: volume in cm² → volume in cm³
1 cm³ holds exactly 1 millilitre of water. That is not a coincidence — it is how the litre was defined.

- Who is the Volume poster for?
- Volume is filed under 5th Grade (ages 10–11), so it matches what that year asks a child to remember. It is equally useful to an older student revisiting math, and to the parent or teacher answering the question at the kitchen table.
- When should you use the Volume poster?
- Build a box out of cubes and count them. Then check the formula gives the same number. A wall chart earns its place by being glanceable from where the work is happening, so Volume belongs on the wall where that math work actually happens, within glancing distance, rather than filed away.
- What other posters go with Volume?
- Adding Unlike Fractions, Area & Perimeter and Sorting Shapes by Their Properties sit alongside Volume in the 5th Grade set. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Adding Unlike FractionsArea & PerimeterSorting Shapes by Their Properties
- Is the Volume poster free to download and print?
- Yes. Volume downloads as a free PDF with no account, no email and no watermark, like everything else in the 5th Grade set. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Volume poster print at?
- Volume is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Volume loses nothing.Printing guide
