Printable Planter Box Soil Layer Volume Worksheet gives learners a diagram, one worked example and five questions. The student sheet leaves space to show work. A second printable page gives the steps for each answer.
Start with the model
Volume counts cubic units. Multiply the area of the rectangular base by the prism height.
The rectangular prism measures 15 cm long, 8 cm wide and 7 cm high.
Worked example
One layer that is 1 cm thick has base area 15 × 8 = 120 cm² and volume 120 cm³.
Ask the learner to point to the information used in the example. When they move on to the exercises, have them record the quantity, unit or label that each step represents.
Practice questions
- Find the volume of the full prism.
- Find the volume up to a height of 5 cm.
- How much volume is lost if a 2 cm layer is removed from the top?
- A second prism has the same base and volume 960 cm³. Find its height.
- If you double the base width and halve the height, does the volume change?
Separate answer key
- 120 × 7 = 840 cm³.
- 120 × 5 = 600 cm³.
- 120 × 2 = 240 cm³.
- 960 ÷ 120 = 8 cm.
- No. The factors 2 and 1/2 cancel. The volume remains 840 cm³.
