Answer:
Into Math Grade 5 Module 5 Lesson 1 Answer Key Use Unit Cubes to Build Solid Figures-1

Explanation:
Given Alexandra is volunteering to stack boxes of soup cans
at a community food bank. She stacks the boxes to
form the right rectangular prism as 2 X 6 X 1 boxes shown.
So made visual models to show three other ways that
Alexandra can stack the boxes to form right
rectangular prisms above as 1. 3 X 1 X 4= 12 boxes,
2. 4 X 1 X 3= 12 boxes and 3. 2 X 1 X 6= 12 boxes.

Turn and Talk In what other ways can Alexandra stack the 12 boxes?
Answer:
1. 1 X 12  x 1 = 12 boxes,
2. 12 X 1 X 1 = 12 boxes and
3. 2 x 2 X 3 = 12 boxes,

Explanation:
Alexandra can stack the 12 boxes in this ways also as
1. 1 X 12 = 12 boxes,
2. 12 X 1 = 12 boxes and
3. 2 x 2 X 3 = 12 boxes.

1. Carlos and Kelly are building store displays in the shape of right rectangular prisms using cube-shaped boxes of the same size.
HMH Into Math Grade 5 Module 5 Lesson 1 Answer Key Use Unit Cubes to Build Solid Figures 3
A. Use unit cubes to make visual models of the two displays.
B. How many cubes are in each visual model?
C. Think of the length of the edge of each cube-shaped box as one unit. What are the dimensions of each display?
Answer:
Into Math Grade 5 Module 5 Lesson 1 Answer Key Use Unit Cubes to Build Solid Figures-2
B. 16 units each,
C. Carlos – 2 units X 2 units X 4 units,
Kelly – 4 units X 2 units X 2 units,

Explanation:
Given Carlos and Kelly are building store displays in the
shape of right rectangular prisms using cube-shaped
boxes of the same size.
A. Used unit cubes to make visual models of the two displays
as shown above,
B. In each visual model there are 16 units,
C. Dimensions of each display is
Carlos – 2 units X 2 units X 4 units,
Kelly – 4 units X 2 units X 2 units.

Connect to Vocabulary
A cube is a type of right rectangular prism. A unit cube is a cube that has a length, width, and height of 1 unit.

D. How many faces and edges does a unit cube have?
E. How many faces and edges does each display have?
F. How can you place Carlos’s display to make it match Kelly’s display exactly?

Answer:
D. 6 faces, 12 edges,
E. 3 faces, 8 edges,
F. Place it horizontally right,

Explanation:
D. A unit cube has 6 faces and 12 edges,
E. Each display have 3 faces and 8 edges,
F. Place Carlos’s display horizontally right to make
it match Kelly’s display exactly.

Turn and Talk How can you tell how many unit cubes make up a right rectangular prism if you cannot see all the unit cubes that make it up?
Answer:
The number of base cubes and number of layers
of unit cubes,

Explanation:
By counting the number of base cubes and
number of layers of unit cubes.

2. For a concert, Angela builds platforms using cube-shaped blocks, each with an edge of 1 unit.
HMH Into Math Grade 5 Module 5 Lesson 1 Answer Key Use Unit Cubes to Build Solid Figures 5
A. Use unit cubes to build a visual model of each platform. How many unit cubes are in each visual model?
B. Which platform has the greatest number of blocks?
Answer:
A.
Into Math Grade 5 Module 5 Lesson 1 Answer Key Use Unit Cubes to Build Solid Figures-3
B. Platform -2 has the greatest number of 8 units blocks,

Explanation:
Given for a concert, Angela builds platforms using cube-shaped blocks,
each with an edge of 1 unit,
A. Used unit cubes to build a visual model of each platform
as shown above, Unit cubes are in each visual model are
Platform 1 – 5 units,
Platform 2 – 8 units,
Platform 3 – 5 units,
B. The greatest number of blocks are in Platform 2 – 8 units blocks.

Turn and Talk How many other platforms can you design using 5 unit cubes? Describe how the platforms are the same and different.
Answer:
More than 5 degins,
same – 5 units only,
designs are different,

Explanation:
We can design different platforms using 5 unit
cubes 1 X 5, 5 X 1 and more the platforms are
same as they have total 5 unit cubes only,
The platforms are different as they have different designs,

Question 3.
Reason Using cube-shaped mini cakes of the same size, a pastry chef creates the larger cake shown for a party. If each mini cake serves one guest, how many servings are in the larger cake? Explain how you know.
HMH Into Math Grade 5 Module 5 Lesson 1 Answer Key Use Unit Cubes to Build Solid Figures 8
Answer:
27 servings,

Explanation:
Given using cube-shaped mini cakes of the same size,
a pastry chef creates the larger cake shown for a party.
If each mini cake serves one guest, number of servings
in the larger cake are we have 3 X 3 X 3 chef has length
3 pastries, wide 3 pastries and height 3 pastries so
in larger cake we have 27 pastries which can
be served to 27 guests.

Question 4.
Open Ended Describe two different right rectangular prisms that can be made using 18 unit cubes.
Answer:
1. 3 units X 3 units X 2 units,
2. 6 units X 3 units X 1 unit,

Explanation:
Two different right rectangular prisms that can be
made using 18 unit cubes are
1. 3 units X 3 units X 2 units = 18 units and
2. 6 units X 3 units X 1 unit = 18 units.

Count the number of unit cubes used to build each solid figure.

What is still unclear about the relationship between rectangular prisms and unit cubes?
___________________
Answer:
Rectangular prism all sides are not equal like
in cube,

Explanation:
A cube has 6 faces which are identical squares
whereas a rectangular prism has 6 faces in which
all the faces are rectangles.
The opposite faces in a rectangular prism are identical.
So in rectangular prism all sides are not equal like
in cube.
