problem_activity: Activity
The purpose of this task is for students to use the Pythagorean Theorem to calculate which rectangular prism has the longer diagonal length. To complete the activity, students will need to picture or sketch the right triangles necessary to calculate the diagonal length.
Identify groups using well-organized strategies to calculate the diagonals. For example, for Prism K some groups may draw in the diagonal on the bottom face of the cube and label it with an unknown variable, such as
\(s\)
, to set up the calculation for the diagonal as
\(\sqrt{6^2+s^2}\)
. Students would then know that to finish this calculation, they would need to find the value of
\(s\)
, which is can be done using the edge lengths of the face of the prism
\(s\)
is drawn on.
The idea that the Pythagorean Theorem might be applied several times in order to find a missing length is taken even further in the extension, where students can apply it over a dozen times, hopefully noticing some repeated reasoning along the way, in order to find the last length.
Launch
Arrange students in groups of 2. Provide access to calculators. Ask students to read and consider the first problem and then give a signal when they have done so. If possible, use an actual rectangular prism, such as a small box, to help students understand what length the diagonal shows in the image. Once students understand what the first problem is asking, poll the class to see which prism they think has the longer diagonal and post the results of the poll for all to see. Select 2–3 students to share why they chose the prism they did. The conversation should illuminate a few key points: Prism K has one edge with length 6 units, which is longer than any of the edges of Prism L, but it also has a side of length 4 units, which is shorter than any of the edges of Prism L. Prism K also has a smaller volume than Prism L.
Give 1 minute of quiet think time for students to brainstorm how they will calculate the lengths of each diagonal. Ask partners to discuss their strategies before starting their calculations. Follow with a whole-class discussion.
Representation: Internalize Comprehension.
Provide access to 3-D models of rectangular prisms (for example, a tissue box) for students to view or manipulate. Use color coding to highlight and make connections between corresponding parts.

Conversing, Writing: MLR5 Co-Craft Questions.
Before revealing the questions in this activity, display only the image of the rectangular prisms. Invite students to work with a partner to write mathematical questions that could be asked about the prisms. Select 1–2 groups to share their questions with the class. Listen for and amplify questions about the lengths of the diagonals. For example, “What is the length of the diagonal of Prism
\(K\)
?” and “Which rectangular prism has the longer diagonal length?” If no student asks these questions, ask students to adapt a question to align with the learning goals of this lesson. Then reveal and ask students to work on the actual questions of the task. This routine will help develop students’ meta-awareness of language as they generate questions about calculating the diagonal length of a rectangular prism.
Design Principle(s): Maximize meta-awareness
Student Facing

Activity Synthesis
Ask groups to share how they calculated the diagonal of one of the rectangular prisms. Display the figures in the activity for all to see and label the them while groups share.
If time allows and no groups pointed out how the diagonal length of the rectangular prisms are the square root of the sum of the squares of the three edge lengths, use Prism K and the calculations students shared to do so. For example, to calculate the diagonal of Prism K, students would have to calculate
\(\sqrt{6^2+\left(\sqrt{41}\right)^2}\)
, but
\(\sqrt{41}\)
is from
\(\sqrt{5^2+4^2}\)
which means the diagonal length is really
\(\sqrt{6^2+5^2+4^2}\)
since
\(\sqrt{6^2+\left(\sqrt{41}\right)^2}=\sqrt{6^2+\left(\sqrt{5^2+4^2}\right)^2}=\sqrt{6^2+5^2+4^2}\)
. So, for a rectangular prism with sides
\(d\)
,
\(e\)
, and
\(f\)
, the length of the diagonal of the prism is just
\(\sqrt{d^2+e^2+f^2}\)
.
