Solid Shapes

Volume Definition

Name the shapes

Volume is the quantity of three-dimensional space enclosed by some closed boundary, for example, the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains.[1] Volume is often quantified numerically using the SI derived unit, the cubic metre. The volume of a container is generally understood to be the capacity of the container, i. e. the amount of fluid (gas or liquid) that the container could hold, rather than the amount of space the container itself displaces.

Amount of H2O with object = ______ About of H2O without object = ______ Difference = Volume = ______

A cube can also be classified as a —

A. rectangular prism.

B. square-based pyramid.

C. cylinder.

D. rhombus. (plane shape)

Use the picture below to answer this question.

How many more small cubes are needed to complete the large cube above?

Directions:

Review questions have been written.

Click the Spin Button.

When the wheel stops, click to view the question.

Groups discuss answer and post their solution.

After the question is discussed, click to check the answer.

How many more small cubes are needed to complete the large cube?

The large cube would have a base of 9 cubes (3 x 3) and the total volume would be 27 cubes.

The bottom row is complete.

The second row needs 2 more cubes

The top row needs 4 cubes.

Six cubes are needed to complete the large cube.

VOLUMES IN REAL LIFE

Volume is the amount of space an object takes up.

The base unit of volume in the metric system in the liter and is represented by L or l.

Standard: 1 liter is equal to one cubic decimeter

NAME THE 3D SOLID FIGURES
