5th Grade Volume

Defining Volume

100

True or False. Volume is the amount of space that an object takes up.

True.

200

Volume is measured in A. Lines B. Squares C. Cubic units

C

300

The formula for volume of a rectangular prism is:

volume = length x width x height

400

Centimeters x centimeters x centimeters = ?

cubic centimeters, or centimeters cubed

500

True or False. You can find the volume of a composite figure (a NON rectangular prism) by using length x width x height

False. You would have to count the cubes, or add up the volumes of the different figures.

Counting Cubes

100

True or False. A cube has six square faces.

True

200

For a composite figure, it's easier to count cubes to find volume. True or False?

True

300

A figure is made out of sugar cubes. If the figure is made of 6 rows, with 5 sugar cubes in each row, how many sugar cubes are there altogether?

6x5=30 sugar cubes

400

I made this figure out of blocks. How many cubes did I use to make the figure? (see slide 10)

120 cubic units

500

How many cubes make up the figure? (See slide 11)

90 cubic units

Volume Formula

100

What is the formula for finding the volume of a rectangular prism?

Volume = length x width x height

or

Volume = base x height

200

I made a tower in the shape of a rectangular prism out of blocks. The length was 8 in, width was 2 in, and height was 4 in. What was the volume of the figure?

8x2x4 = 64 cubic inches

300

What is the volume of the figure that is 2ft x 3ft x 6ft? 

36 cubic feet

400

A box is 9 inches by 11 inches by 8 inches. What is the volume of the box?

792 cubic inches

500

What is the volume of a figure that is 2ft x 6ft x 7ft? 

84 cubic cm

Finding the Missing Side

100

Double! How do you find the height if the volume, length, and width are given to you.

Divide the volume by the product of length x width OR multiply length x width and then guess-multiply for the height until you get the volume

200

Volume = 4 cubic inches, length = 2 inches, width = 2 inches, height = ?

Height = 1 inch

300

Volume = 12 cubic feet, width = 2 feet, height = 2 feet, length = ?

length = 3 feet

400

Volume = 56 cubic feet, length = 7 feet, width = 2 feet, height = ?

height = 4 feet

500

Double!! Volume = 300 cubic cm, length = 10 cm, width = 6 cm, height = ?

height = 5 cm
