McGraw-Hill Math Grade 5 Answer Key Chapter 10 Lesson 9 Measuring Volume with Unit Cubes
Count
Count the cubes in each solid object. Write the volume.
Question 1.
Question 2.
Answer:
In the above object we can observe 4 rows. There are total 7 cubes in each row.
7 + 7 + 7 + 7 = 28 cubes
In one layer there are 28 cubes.
Now we have to add the number of cubes in each layer.
There are three layers in the above object.
28 + 28 + 28 = 84 cubes
The total number of cubes in the above object are 84.
Volume = length x width x height
volume = 4 in x 7 in x 3 in = 84 cubic inches
Since the measure is in inches, the volume of the object is 84 cubic inches.
Question 3.
Look at the cubes below. Write a number sentence to find the volume. Use specific units.
Answer:
Volume (V) = length x width x height
V = 3 cm x 8 cm x 2 cm
V = 48 cubic centimeters
Since the measure is in centimeters, the volume of the object is 48 cubic centimeters.
