Solving Exercise 1 - Math 5 Page 115
Problem Statement:
In the two figures below:
How many small cubes does rectangular box A consist of?
How many small cubes does cube B consist of?
Which figure could have a larger volume?
Solution Method:
- Student observes the given figures, calculates the number of small cubes in each figure
- After calculation, student compares to see which figure has more small cubes, indicating it may have a larger volume.
Answer:
Rectangular box A consists of 16 small cubes.
Rectangular box B consists of 18 small cubes.
Solving Exercise 2 - Math 5 Page 115 Workbook
Problem Statement:
How many small cubes does Figure A consist of?
How many small cubes does Figure B consist of?
Compare the volumes of figures A and B.
Solution Method:
- Student observes the given figures, calculates the number of small cubes in each figure
- After calculation, student compares to see which figure has more small cubes, indicating it may have a larger volume.
Answer:
Figure A consists of 45 small cubes.
Figure B consists of 26 small cubes.
The volume of Figure A is greater than the volume of Figure B (or the volume of Figure B is less than the volume of Figure A).
