Title of Lesson: How Much Do They Hold?
UFTeach Students’ Names: Meghan Wilder
Teaching Date and Time: Monday, April 7, 2014; 9:15 AM
Length of Lesson: 50 minutes
Grade / Topic: 6th – Advanced/Volume of Rectangular Prisms
Source of the Lesson: http://illuminations.nctm.org/Lesson.aspx?id=2927
http://www.mathsisfun.com/definitions/rectangular-prism.html
Appropriateness for Middle School Students: In this lesson, students will be working in pairs. Having students
working in pairs will allow them to develop vital communication and cooperation skills necessary for molding
them into productive members of society. Group work will also allow the students to learn how to collaborate
with their peers and exchange thoughts and ideas freely. Additionally, this lesson will allow the students to be
hands-on; the students will be constructing models of rectangular prisms, which will help them visualize the
connection between the volumes of the prisms and their dimensions.
Concepts: A prism is a three-dimensional figure with two congruent parallel bases and rectangular faces for
sides. The different parts that contribute to a prism are vertices, edges, bases, and faces. This threedimensional figure is named by the polygon that makes up its base; therefore, there are multiple types of
prisms, including hexagonal, rectangular, and triangular. These prisms can be found everywhere, ranging from
a cereal box to all the way to the Pyramids in Egypt. This lesson will focus on the rectangular prism, more
specifically on the volume of rectangular prisms. Volume is the measure of how much space a threedimensional object can take up or the amount it can hold. When measuring the volume, cubic units are used
because three dimensions, the base, width, and height, are multiplied together. Another way to find the
volume is to consider how many unit cubes it can contain. A unit cube is a simple cube used to measure one
inch, one centimeter, or whatever the units of measurement being used are on all sides. In this lesson,
students will discover the meaning of the equation of volume for the rectangular prism. Mastering this
concept will help the students to determine the volume of other prisms, such as the triangular prism; this will
in turn prepare students for future mathematics courses and other physical sciences. Additionally, developing
an understanding of the volume of rectangular prisms will help students recognize the amount of material a
prism, such as a pool, can hold or the amount of material is needed to make a rectangular prism in everyday
life.

2. Find the width of a rectangular
prism when its volume is 216 in3
and has a base of 6 in. and height
of 12 in.
V = bwh
V = (9 m)(4 m)(6 m)
V = 216 m3
V = bwh
216 in3 = (6 in.)w(12 in.)
216 in3 = (72 in2)w
w = 3 in.
V = ____216 m3_____
w = _____3 in._____
3. Find the height of a rectangular
prism with a volume of 154 ft3,
width of 2 ft, and base of 11 ft.
4. Find the base of a rectangular
prism when its volume is 240 cm3
and has a width of 4 cm and height
of 15 cm.
V = bwh
154 ft3 = (11 ft)(2 ft)h
154 ft3 = (22 ft2)h
h = 7 ft
V = bwh
240 cm3 = b(4 cm)(15 cm)
240 cm3 = (60 cm2)b
b = 4 cm
h = ____7 ft_____
b = _____4 cm______
