Solving Math Grade 5 Page 45 VBT Workbook Volume 2, Focused Practice, Exercise 120
1. Solve Exercise 1 - Math Exercise Book Grade 5 Volume 2 Page 45
3 cubic meters = 3000 cubic decimeters = 3000 liters
The number of liters of water in the tank is:
3000 x 4/5 = 2400 (liters)
Answer: 2400 liters.
2. Solve Problem 2 - Math Exercise Book Grade 5 Volume 2 Page 45
Problem:
Given a cube with a side length of 0.5m. Calculate and write the result in the blank:
Surface area around:
Total surface area: ...
Volume: ...
Solution Method
Applying the formulas:
- Surface area around = area of one side x 4 = side x side x 4.
- Total surface area = area of one side x 6 = side x side x 6.
- The volume V is: V = side x side x side.
Answer
Surface area around the cube:
Sxq = 0.5 ⨯ 0.5 ⨯ 4 = 1 (m2)
Total surface area of the cube:
Dtp = 0.5 ⨯ 0.5 ⨯ 6 = 1.5 (m2)
Volume of the cube:
V = 0.5 ⨯ 0.5 ⨯ 0.5 = 0.125 (m3)
3. Solve Problem 3 - Math Exercise Book Grade 5 Volume 2 Page 45
Problem:
a. Write the appropriate measurement in the blank:
b. Write the appropriate number in the space:
The length of shape (1) is ...... times the length of shape (2)
The width of shape (1) is ...... times the width of shape (2)
The height of shape (1) is ...... times the height of shape (2)
The volume of shape (1) is ...... times the volume of shape (2)
Solution Method
Volume = length ⨯ width ⨯ height (same unit of measurement).
Answer
a.
b.
The length of shape (1) is 2 times the length of shape (2)
The width of shape (1) is 2 times the width of shape (2)
The height of shape (1) is 2 times the height of shape (2)
The volume of shape (1) is 8 times the volume of shape (2)
