Worksheet directions

Grade 6 • Guided Practice • Work with your teacher or a partner. Discuss the model or strategy, then complete each problem.

Sample questions

1. A right rectangular prism has edges 1, 1 and 2/3 meters. Find V using both lwh and Bh, naming B.
2. A student counts 16 cubes of edge 1/2 meter and reports 8 m³. Explain the error and find the correct volume.
3. Draw a rectangular prism with edges 1, 1 and 2/3 meters. Show how unit-fraction cubes could fill it and compare the counting result with lwh.
4. Edge measurements are in meters. Each small cube has edge 1/2 m. Count the cubes along each dimension and calculate the prism’s volume.
5. A right rectangular prism is 3/2 m long, 1 m wide and 1/2 m high. Imagine filling it with cubes whose edges are 1/2 m. How many cubes fit along each dimension, how many fit in all, and what is the prism’s volume?
6. Draw a rectangular prism with edges 2/3, 1 and 2/3 meters. Show how unit-fraction cubes could fill it and compare the counting result with lwh.
