Volume of Rectangular Prism

Volume of Rectangular Prism


This educational poster provides a clear, step-by-step explanation of how to calculate the volume of rectangular prisms. It includes a definition of volume, the volume formula, and a worked example to show students exactly how to solve volume problems.


Key features:


Illustrates the three dimensions used to calculate volume - length, width and height

Highlights the volume formula: Volume = Length x Width x Height

Uses a sample prism with labeled dimensions to model how to substitute the values into the formula

Emphasizes that volume is always cubed, not just multiplied

Shows the order of operations to follow when calculating volume

This math poster acts as a helpful visual aid to reinforce concepts for finding the volume of rectangular prisms. It can be displayed in the classroom as an easy reference for students. The worked example supports their understanding of this 3D geometry topic.


An excellent addition to elementary and middle school math classrooms when teaching students about volume, geometry formulas, and multidimensional shapes. They will grasp the concept clearly with this step-by-step volume poster! As with all of our resources, it is customizable so you can tailor this resource for your class.

    Recognize volume as an attribute of solid figures and understand concepts of volume measurement.


    Measure volumes by counting unit cubes, using cubic cm, cubic in, cubic ft, and improvised units.


    Relate volume to the operations of multiplication and addition and solve real world and mathematical problems involving volume.


    Find the volume of a right rectangular prism with fractional edge lengths by packing it with unit cubes of the appropriate unit fraction edge lengths, and show that the volume is the same as would be found by multiplying the edge lengths of the prism. Apply the formulas 𝘝 = 𝘭 𝘸 𝘩 and 𝘝 = 𝘣 𝘩 to find volumes of right rectangular prisms with fractional edge lengths in the context of solving real-world and mathematical problems.


    Solve real-world and mathematical problems involving area, volume and surface area of two- and three-dimensional objects composed of triangles, quadrilaterals, polygons, cubes, and right prisms.


    Know the formulas for the volumes of cones, cylinders, and spheres and use them to solve real-world and mathematical problems
