### Eureka Math Grade 5 Module 5 Lesson 2 Problem Set Answer Key

Question 1.
Shade the following figures on centimeter grid paper. Cut and fold each to make 3 open boxes, taping them so they hold their shapes. Pack each box with cubes. Write how many cubes fill each box.
a. Number of cubes: ____________

Number of cubes = 8

b. Number of cubes: ____________

Number of cubes =  16

c. Number of cubes: ____________

Number of cubes = 48

Question 2.
Predict how many centimeter cubes will fit in each box, and briefly explain your predictions. Use cubes to find the actual volume. (The figures are not drawn to scale.)
a. Prediction: _________________
Actual: ____________________

Prediction : 8 cubic centimetres

Actual : 8 cubic centemetre

2 rows by 4 colums

= 4 x 2 = 8 cubes of each 1 sq. cm

Therefore, the total number of cubes = 8 cubic centimeters

b. Prediction: _________________
Actual: ____________________

Prediction : 16

Actual : 16

2 rows x 4 columns multiplied by 2

2 x 4 x 2 = 16

Therefore, number of cubes = 16

c. Prediction: _________________
Actual: ____________________

Prediction : 40

Actual : 40

2 rows x 5 columns multiplied by 4

2 x 5 x 4 = 40

Therefore, total number of cubes = 40

Question 3.
Cut out the net in the template, and fold it into a cube. Predict the number of 1-centimeter cubes that would be required to fill it.
a. Prediction: ____________________
c. How many 1-centimeter cubes are used to fill the figure? Was your prediction accurate?

Prediction: 1 cube

I know that the net has 6 faces, When I folded the net it is in the shape of cube so, it cannot be a open box.

Question 1.
If this figure were to be folded into a box, how many cubes would fill it? Number of cubes: _____________

8

Question 2.
Predict how many centimeter cubes will fit in the box, and briefly explain your prediction. Use cubes to find the actual volume. (The figure is not drawn to scale.) Prediction: _________________
Actual: ____________________

Prediction : 12

Rows = 2 and

Columns = 3

2 layers

Now, 2 x 3 x 2 =12

Therefore, total number of cubes = 12

### Eureka Math Grade 5 Module 5 Lesson 2 Homework Answer Key

Question 1.
Make the following boxes on centimeter grid paper. Cut and fold each to make 3 open boxes, taping them so they hold their shape. How many cubes would fill each box? Explain how you found the number.
a. Number of cubes: _____________

b. Number of cubes: _____________

c. Number of cubes: _____________

Question 2.
How many centimeter cubes would fit inside each box? Explain your answer using words and diagrams on each box. (The figures are not drawn to scale.)
a. Number of cubes: ____________________

Explanation:

2 rows and 3 columns ( Each cube measures 1 cm

So, 2 x 3 = 6

b. Number of cubes: ____________________

Explanation:

2 rows x 3 columns multiplied by 2

6 x 2 = 12 cubes

c. Number of cubes: ____________________
Explanation:

2 rows x 4 columns multiplies by 4

2 x 4 x 4 = 32

Question 3.
The box pattern below holds 24 1-centimeter cubes. Draw two different box patterns that would hold the same number of cubes.
