Chapter 11
For chapter 11 I learn about area and volume about prism and 3D . There are triangular prism, rectangular prism, parallelogram, and more. We made the sample of prism using origami paper. Then we did some classwork from 11:01, 11:04-11:05. We also make a written report about the value of Pi.
Area is the size of a surface. This are the formula of each shape:
Volume is the amount 3 dimensional space of an object occupies. For this example the volume is 4×5×10 = 200 units3.
A prism is a solid object with identical ends, has flat sides and the same cross section all along it's length.
These are the example of prism and their cross section:
Triangular prism is a prism with the cross section of a triangle. The characteristic of triangular prism are the cross section of this object is a triangle and it has the same cross section all along its length.
Rectangular prism or cuboid is a 3 dimensional object which has six faces. It has the same cross-section along a length, which makes it a prism. Example: boxes like our shoe box
A Parallelogram is a flat shape with opposite sides parallel and equal in length. The characteristic of parallelogram are has two pair of opposite sides. One side has another side that has the same measurement of length.
Then we made a chart to measure the circumference, the diameter, radius, and the relationship between circumference and diameter. We measure 5 objects that are circular.
Awesome blog! You've explain a lot of information about what you've learned in this blog.
