Surface area and volumen with base 10 blocks.

Are you the kind of person that needs to touch to learn. This lesson uses base 10 blocks (10x0x10 cubes, 10x10x1 flats, 10x1x1 longs and 1x1x1 unit cubes). A cocodrile is smiling to you throughout the lesson while you find the surface area and volume of these individual components, or the composite solids made up of a combination of several of them stacked to model for example a multistory building.

You will learn how to project the views and how to get the minimum amount of these views to represent the solid figure. For each of these problems you will be able to anticipate the solution by woking the problem before runing it. You accomplish this using the MARKER TOOLS MENU at the top of the screen. It has a pen, a highlighter and an eraser. Once you worked the problem you may check the solution by running the problem. Drawings give perspective with corner views, and technicians use foundational representations of buildings to do their projects. You will learn this and more...

Lesson's Glossary

A segment that helps to make up a face.

A polygonal region of a surface.

Hidden lines
Broken lines used to signify lines that normally wouldn't be seen in a drawing.  

Lateral area.

Lateral area
The area of the lateral surface of a solid.

Lateral edge
A segment whose endpoints are corresponding points of a cylindrical solid's bases, or whose endpoints are the vertex of a conic solid and a vertex of its base.

Lateral faces
The faces of the lateral surface of a prism, or a face of a pyramid that is not a base.

Lateral surface
- the surface not included in the base (s).

A prism whose opposite faces are all parallelograms and congruent (in pairs).

Feeling of depth.

Perspective drawing
A drawing in which, in order to show perspective, oblique parallel lines will meet.

A three-dimensional surface which is the union of polygonal regions and has no holes.

It is a polyhedron that has two congruent and parallel faces, called bases. The remaining faces, which are parallelograms are called lateral faces. The altitude is the perpendicular segment whose endpoints are at the bases. The length of the altitude is the height of the prism. A right prism is one with all lateral faces rectangles. An oblique rectangle has some to be nonrectangular.  

Right prism
A prism whose direction of sliding is perpendicular to the plane of the base.

The union of the surface and the region of space enclosed by a 3-D figure.

Solid geometry
The study of figures in three-dimensional space.

The set of all possible points; made up of infinite planes.

The boundary of a 3-D figure.

Surface area
The total area of the surface of a solid.

Unit cube
Unit of measuring volume.
