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: ____________
Answer:
Number of cubes = 8
b.
Number of cubes: ____________
Answer :
Number of cubes =Â 16
c.
Number of cubes: ____________
Answer:
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: ____________________
Answer:
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: ____________________
Answer:
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: ____________________
Answer:
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: ____________________
b. Explain your thought process as you made your prediction.
c. How many 1-centimeter cubes are used to fill the figure? Was your prediction accurate?
Answer:
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: _____________
Answer:
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: ____________________
Answer:
Prediction : 12
Answer :12
Rows = 2 and
Columns = 3
2 layers
Now, 2 x 3 x 2 =12
Therefore, total number of cubes = 12

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: ____________________
Answer: 6
Explanation:
2 rows and 3 columns ( Each cube measures 1 cm
So, 2 x 3 = 6
b.
Number of cubes: ____________________
Answer : 12
Explanation:
2 rows x 3 columns multiplied by 2
6 x 2 = 12 cubes
c.
Number of cubes: ____________________
Explanation:
Answer: 32
2 rows x 4 columns multiplies by 4
2 x 4 x 4 = 32
