Lesson

Are you ready?

We have counted squares to find the area of a shape and can use that to help us find the volume in this lesson. Let's try this problem to review.

Find the area of the shape by counting the number of grid squares it covers.

Each grid square represents $1$1 square unit.

This video introduces the unit cube and how it can be used to measure how much space an object takes up, which is its volume.

Question

In this figure, $1$1 block $=$= $1$1 cm3.

What is the volume of the solid figure?

 

Remember!

We can count the number of unit cubes one at a time, or multiply the number of rows by the number of columns.

Outcomes

5.MD.C.3a

Recognize volume as an attribute of solid figures and understand concepts of volume measurement. A. A cube with side length 1 unit, called a “unit cube,” is said to have “one cubic unit” of volume, and can be used to measure volume.

5.MD.C.3b

Recognize volume as an attribute of solid figures and understand concepts of volume measurement. B. A solid figure which can be packed without gaps or overlaps using n unit cubes is said to have a volume of n cubic units.

5.MD.C.4

Measure volumes by counting unit cubes, using cubic cm, cubic in, cubic ft, and improvised units.
