Solve Exercise 1 - Grade 5 Math Exercise Book Volume 2 Page 34

Problem Statement:

Fill in the blank with the appropriate measurement:

Solution Method:

To calculate the volume of a rectangular prism, multiply the length by the width, then multiply by the height (using the same unit of measurement).

Answer Key

Volume of rectangular prism (1):

V = 6 ⨯ 4 ⨯ 5 = 120cm³

Volume of rectangular prism (2):

V = 2.5 ⨯ 1.8 ⨯ 1.1 = 4.95m³

Volume of rectangular prism (3):

V = 3/4 x 1/3 x 2/5 = 1/10 dm³

We have the result table as follows:

Problem Statement:

Calculate and compare the volumes of the two rectangular prisms below:

Solution Method:

- Calculate the volumes of the shapes and compare the results.

- To calculate the volume of a rectangular prism, multiply the length by the width, then multiply by the height (using the same unit of measurement).

Volume of rectangular prism (a) is:

1.5 ⨯ 0.8 ⨯ 1 = 1.2 (m³)

Volume of rectangular prism (b) is:

1.5 ⨯ 0.8 ⨯ 1 = 1.2 (m³)

So the volume of rectangular prism (a) equals the volume of rectangular prism (b)

3. Solving Exercise 3 - Math Exercise Book Grade 5 Volume 2 Page 35

Problem Statement:

Calculate the volume of the wooden block as shown in the figure:

Solution Method:

Divide the wooden block into 2 rectangular prisms (1) and (2) then calculate the volume of each prism.

The volume of the wooden block equals the sum of the volumes of the two rectangular prisms (1) and (2).

Answer Key

Divide the wooden block into 2 rectangular prisms as shown in the diagram.

The length of rectangular prism (1) is:

20 - 12 = 8 (cm)

The volume of rectangular prism (1) is:

8 x 8 x 10 = 640 (cm³)

The height of rectangular prism (2) is

10 - 5 = 5 (cm)

The volume of rectangular prism (2) is:

12 x 8 x 5 = 480 (cm³)

The volume of the wooden block is:

640 + 480 = 1120 (cm³)

Answer: 1120cm³.
