Guidelines for solving Exercise 2 on page 115 of Mathematics Grade 5 textbook
Problem:
How many small cubes make up shape A?
How many small cubes make up shape B?
Comparing the volumes of shapes A and B.
Solution Method:
- Observe the provided illustration, calculate the number of small cubes in each shape.
- After calculation, compare which shape has more small cubes; that shape may have a larger volume.
Answer:
Shape A consists of 5 x 3 x 3 = 45 small cubes.
Shape B consists of 3 x 3 x 3 -1 = 27 - 1 = 26 (small cubes).
The volume of shape A is greater than the volume of shape B (or the volume of shape B is smaller than the volume of shape A).
