Rectangular Prism Volume Surface Area Practice Activities
Printable Class 5 maths worksheets for practising volume and surface area of rectangular prisms, using cuboids, nets, unit cubes and labelled dimensions.
Practice that builds confidence
Building the idea of a rectangular prism
These Class 5 geometry worksheets help children understand rectangular prisms, also called cuboids, by connecting length, breadth and height to space inside a solid and area on its outside faces. Learners practise finding volume in cubic units and surface area in square units without treating the two ideas as the same.
The printable activities include labelled prisms, nets, face-area calculations, unit-cube reasoning and word problems based on boxes and cuboid shapes. Children move from visual counting to using formulas, while checking units and interpreting diagrams carefully.
A rectangular prism is a solid with 6 rectangular faces, 12 edges and 8 vertices. In Class 5 maths, children often know it as a cuboid. These worksheets make the shape less abstract by showing boxes, nets and diagrams marked with length, breadth and height. Children learn that changing one dimension changes the whole solid, not just one face.
Volume: space inside the cuboid
Volume tells how many unit cubes can fit inside a rectangular prism. A child may first count layers of cubes, then connect the pattern to length × breadth × height. For example, a cuboid 6 cm long, 4 cm broad and 3 cm high has 6 × 4 × 3 = 72 cubic centimetres. The worksheets encourage children to write cubic units, such as cm³, because volume measures three-dimensional space.
Surface area: covering all outside faces
Surface area is different from volume. It is the total area of the outside faces, measured in square units. Children practise finding the area of each rectangular face and then adding all 6 faces. They may also use pairs of equal faces: 2(lb + bh + lh). Nets help children see why every face must be counted, including the top, bottom, front, back and both sides.
A simple parent routine
At home, ask your child to pick a small box and name its length, breadth and height. First discuss what would fit inside it: that is volume. Then discuss how much paper would cover the outside: that is surface area. After one worksheet, ask the child to explain one answer aloud, including the unit. This quick habit reveals whether they understand the concept or are only copying a formula.
Classroom use for teachers
Teachers can use these pages for geometry practice, revision after introducing cuboids, maths centres or small-group support. The mix of diagrams, nets and word problems helps identify who can calculate correctly and who still needs to visualise faces and layers. Problems can also be used for board discussion by comparing two prisms with different dimensions.

Answers and answer key support
After the child completes the worksheet independently, parents and teachers can use the answer support or answer key information to check the work, review mistakes, and choose the next practice step.
Common errors and why iBloom worksheets help
Children may mix up cm² and cm³, add dimensions instead of multiplying for volume, count only four faces for surface area, or use the same formula for every question. A child-friendly strategy is: “Inside means cubes, outside means faces.” iBloom worksheets build this distinction step by step, with clear diagrams, space for working and varied question formats so learners practise both reasoning and calculation.
Helpful answers
Frequently asked questions
What is the difference between volume and surface area of a rectangular prism?
Volume measures the space inside the rectangular prism and is written in cubic units, such as cm³. Surface area measures the total area of the outside faces and is written in square units, such as cm².
Are rectangular prism and cuboid the same for Class 5 maths?
Yes. In most Class 5 maths lessons in India, a rectangular prism is commonly called a cuboid. Both terms describe a solid with rectangular faces, length, breadth and height.
Do these worksheets use nets of cuboids?
Yes. Nets are included to help children see all six faces of a cuboid and understand why each face contributes to the total surface area.
Which formula should my child use for volume?
For a rectangular prism or cuboid, volume is found by multiplying length × breadth × height. Children should also write the answer in cubic units.
What mistakes should I look for while checking these worksheets?
Watch for missing units, writing cm² for volume, writing cm³ for surface area, forgetting the top or bottom face, and adding length, breadth and height instead of multiplying for volume.
Is this Class 5 rectangular prism volume surface area worksheet free?
Yes. You can preview it for free and use the printable worksheet for home or classroom practice.
Can I download this Class 5 rectangular prism volume surface area worksheet as a PDF?
Yes. Use the worksheet download option to save a printable PDF, or print the worksheet directly from the page.
