Line segment

One of the important topics in geometry is a line segment. I already discussed with you what is perpendicular lines, you can check my previous post.

I have a definition on line segment mentioned below.

Definition of a line segment:- Line segment is defined as, the points, which is joining on the both directions in a specific distance. In between the points distance in a line is called as line segment. A line segment is a smaller part of straight long and a thin line. It has two end points on both the sides.

Now you are aware of what is line segment right..how useful did you find this point, let me know.

You can follow my blogs for slope formula. I hope this was useful.

volume of a rectangle

Friends i have some simple problems to learn how to find the volume of a rectangle. Observe the problems below, it also contains the formula which is used to find the volume of a rectangle.

Problem 1

Find the volume of a rectangle prism whose length l = 4 m and height = 6 m and width = 3m?

Sol:

Formula: volume of rectangle = l × h × w

= 4 × 6 × 3

= 72m2

Problem 2

The wooden box has volume 400m, width 10m and length 20m, Find its height?

Sol: h = ?, w = 10m, l = 20m

volume of rectangle = l × h × w

400 = 20 × h × 10

h = 400/200

h = 2m

Working on simple geometry problems, i also was thinking of working on simple algebra problems in my next post, do you have some sample questions that you want me to discuss....? Let me know that.

You can follow my blogs for pre algebra tutoring. I hope this was useful.
