Volume of Rectangular Prism Example

Grades 5-6Key Stage 2-3Årskurs 5-6

Problem

Find the volume of a box with length 8 cm, width 5 cm, and height 3 cm.

📝Step-by-Step Solution

Recall the formula

Volume of a rectangular prism = length × width × height

V = l × w × h

Identify the dimensions

Length (l) = 8 cm, Width (w) = 5 cm, Height (h) = 3 cm

Substitute into the formula

V = 8 × 5 × 3

Calculate step by step

8 × 5 = 40, then 40 × 3 = 120

8 × 5 × 3 = 120

Add cubic units

Volume is measured in cubic units. The answer is 120 cm³.

V = 120 cm³

✅Final Answer

120 cm³

Volume measures the space inside a 3D object. For rectangular prisms (boxes), multiply all three dimensions. Always use cubic units (cm³, m³, in³, ft³). The volume tells you how many unit cubes fit inside the shape.

Build the assessment, not just the questions

MathQuizily helps teachers move from a topic or standard to a printable math test with answer keys, balanced difficulty, and classroom-ready PDF output.

A useful assessment should make the learning target clear, cover the intended skills, and give the teacher enough information to review the result before students see it. The workflow supports short quizzes, chapter checks, diagnostic tests, homework packets, make-up assessments, and equivalent retake versions.

Choose a grade, topic, curriculum context, and difficulty level. The generated PDF includes a student version and a separate worked answer key, so teachers can print, review, and grade without reformatting questions or building solutions from scratch. No student account is required to create or print a test.
