## McGraw-Hill Math Grade 5 Answer Key Chapter 10 Lesson 8 Counting Unit Cubes and Volume

**Count**

**Count the cubes in each object. Write the total.**

Question 1.

Question 2.

Answer:

Explanation:

In the above object we can observe 3 rows. There are total 3 cubes in each row.

3 + 3 + 3 = **9 cubes**

In one layer there are 9 cubes.

Now we have to add the number of cubes in each layer.

There are three layers in the above object.

9 + 9 + 9 =** 27 cubes**

The total number of cubes in the above object are **27**.

Question 3.

Answer:

Explanation:

In the above object we can observe 3 rows. There are total 2 cubes in each row.

2 + 2 + 2 = **6 cubes**

In one layer there are 6 cubes.

Now we have to add the number of cubes in each layer.

There are four layers in the above object.

6 + 6 + 6 + 6 = **24 cubes**

The total number of cubes in the above object are** 24**.

Question 4.

Answer:

Explanation:

In the above object we can observe 2 rows. There are total 3 cubes in each row.

3 + 3 = **6 cubes**

In one layer there are 6 cubes.

Now we have to add the number of cubes in each layer.

There are three layers in the above object.

6 + 6 + 6 = **18 cubes**

The total number of cubes in the above object are **18**.

Question 5.

Answer:

Explanation:

In the above object we can observe 5 rows. There are total 1 cubes in each row.

1 + 1 + 1 + 1 + 1 = **5 cubes**

In one layer there are 5 cubes.

Now we have to add the number of cubes in each layer.

There are three layers in the above object.

5 + 5 + 5 = **15 cubes**

The total number of cubes in the above object are** 15**.

Question 6.

Answer:

Explanation:

In the above object we can observe 4 rows. There are total 2 cubes in each row.

2 + 2 + 2 + 2 = **8 cubes**

In one layer there are 8 cubes.

Now we have to add the number of cubes in each layer.

There are two layers in the above object.

8 + 8 = **16 cubes**

The total number of cubes in the above object are **16**.
