Volume

Front

Matter Noun

---

[mat-er]

Back

Matter

---

Anything that has mass and takes up space by having volume, constituting the physical substance of the universe.

---

Example: This diagram shows how particles are arranged in solids, liquids, and gases, which explains their properties, including why gases expand to fill any volume.

Front

Mass Noun

---

[mas]

Back

Mass

---

A measure of the amount of matter in a physical body or object, determining its inertia and gravitational attraction.

---

Example: This image shows a balance scale comparing the mass of an apple to a 1-gram weight, demonstrating that the apple has more mass.

Volume Noun

---

[vol-yoom]

Back

Volume

---

The amount of three-dimensional space that a substance or an object occupies or that is enclosed within a container.

---

Example: This image shows a rectangular prism with its three dimensions—length, width, and height—clearly labeled, which are multiplied together to calculate its volume.

Front

Cubic Meter (m³) Noun

---

[kyoo-bik mee-ter]

Back

Cubic Meter (m³)

---

The basic SI (International System of Units) unit for measuring volume, representing the space of a one-meter-sided cube.

---

Example: This image shows that a cubic meter is the amount of space inside a cube that measures 1 meter in length, 1 meter in width, and 1 meter in height.

Front

Liter (L) Noun

---

[lee-ter]

Back

Liter (L)

---

A common metric unit used to measure the volume of liquids, which is equal to 1,000 cubic centimeters.

---

Example: This image shows a 1-liter bottle next to other common containers, helping to visualize the amount of space a liter occupies by comparison.

Front

Displacement Method Noun

---

[dis-pleys-muhnt meth-uhd]

Back

Displacement Method

---

A technique for measuring the volume of an irregularly shaped solid by measuring the volume of fluid it displaces.

---

Example: Submerging an object in a liquid-filled graduated cylinder causes the liquid level to rise. The volume of the displaced liquid equals the volume of the object.

Front

Graduated Cylinder Noun

---

[graj-oo-ey-tid sil-in-der]

Back

Graduated Cylinder

---

A piece of laboratory equipment used to measure the volume of a liquid, marked with increments for precise readings.

---

Example: This diagram shows how to measure the volume of a liquid in a graduated cylinder by reading the measurement at the bottom of the curved surface, called the meniscus.

Front

Prism Noun

---

[priz-uhm]

Back

Prism

---

A three-dimensional solid object with two identical and parallel bases, and whose other faces are all parallelograms.

---

Example: This diagram shows a triangular prism with its key dimensions labeled: length (l), base of the triangle (b), and height of the triangle (h).

Front

Rectangular Prism Noun

---

[rek-tang-gyuh-ler priz-uhm]

Back

Rectangular Prism

---

A three-dimensional solid shape, also known as a cuboid, which has six faces that are all rectangles.

---

Example: This image shows a cereal box as a real-world example of a rectangular prism, with its length, width, and height labeled for calculating volume.

Front

Pyramid Noun

---

[pir-uh-mid]

Back

Pyramid

---

A three-dimensional solid with a polygon base and triangular sides that meet at a single point called the apex.

---

Example: This diagram shows a 'planning pyramid,' a tool for organizing lesson concepts by importance, which is unrelated to the geometric concept of a pyramid's volume.
