How To: Use Heron's formula

Area of a triangle can be calculated when you have the length of its base and height. In this case the area is 1/2 times the base and its height. If you do not know the height of the triangle but know the lengths of all the sides of the triangle then you can calculate its area using the Herons formula. First to use it you need to computer the semi perimeter of the triangle S, which is S = (a + b + c)/2, where a, b, c are the lengths of the sides of the triangle. Now the area of the triangle i...

How To: Create loose, beachy waves with a deep waver

Unlike its name suggests, beachy waves aren't an easy, carefree hairstyle you can achieve simply by hitting up the beach for a day and letting the sun and surf do its work. In fact, if you did just that you'd probably end up with fried, damanged, and dry hair that doesn't look the least "beachy" and pretty.

How To: Use a protractor to measure the height of any object

In this video, we learn how to use a protractor to measure the height of any object. First, attach a level to the protractor, followed by a straw at the 45 degree angle. Next, walk back form the object while looking through the straw. Keep walking back until you spot the top of the object through the straw, then measure to the base of the object. After this, you will have an isosceles triangle that has two equal sides. Use these sides to help find what the size of the object is. After this, a...

How To: Calculate the height and volume of a pyramid

Need to know how to calculate the height and volume of a pyramid in geometry? Learn how with this free video lesson. From Ramanujan to calculus co-creator Gottfried Leibniz, many of the world's best and brightest mathematical minds have belonged to autodidacts. And, thanks to the Internet, it's easier than ever to follow in their footsteps (or just finish your homework or study for that next big test).

How To: Find the volume of a cube, cylinder, pyramid or cone

This video shows the method to find the volume of a cube, cylinder, pyramid or cone. Volume is equal to the multiple of the area of the base and the height or V=(base area)(height). Starting with the cube, the volume= [(side)(side)](side) or side cube or side^3. In the video side=50m or V=125000 cubic centimeter. Volume of the cylinder= [(pi){(radius of base)^2}](height of cylinder) or V=(pi)(r^2)(h). Substituting the values, V=pi(2^2)(4) cubic inches or 16pi cubic inches. Volume of a pyramid...

How To: Fill a cone

This is a very interesting instructional video on how to fill a cone. Pour oil into a cone of diameter 30 inches and depth 40 inches. Now find the volume of the oil as a function of its depth. Volume = 1 over 3 phi rsquare h. We don't know the height and depth of the oil poured into the cube. Draw similar right angled triangles. In one right angled triangle the height is 40 inches and in the other triangle it is h. Similarly the height is 40 inches and h respectively. Now rover h =15 over 40....

How To: Find the area of a parallelogram and a triangle

This video shows you how to easily find the area of a parallelogram and the area of a triangle. The first part of the video teaches you how to find the area of a paralellogram. The area of a parallelogram is BxH, where B is the base and H is the height. The height is obtained by drawing a perpendicular line from one corner to the base. The second part of the video teaches you how to find the area of a triangle. The area of a triangle is (BxH)/2, where B is the base and H is the height. That's...

How To: Draw a rectangle

In this tutorial the author shows how to draw a rectangle with given base b and height h values. First she uses a ruler to draw a horizontal base line of b cm. Now she uses a protractor and marks a 90 degree angle at one end of the line, then draws a straight line of h cm which is the height of the rectangle. Now she finishes the remaining part of the rectangle by drawing similar lines of the other sides. This video clearly explains how to draw a rectangle given the values of its base and hei...

How To: Find surface area of a prism using a specific example

In this video, we learn how to find the surface area of a prism using a specific example. First you will need to find the base and height of your prism. If the base edge is 6 and the height is 8 you will do the equation Area= 1/2 bh. Doing this math out on your calculator, you will get the answer of 12.39. This is what the size of each triangle in the prism is going to be. The area of one pentagon (or the base) is 61.92 inches squared. If you need help with this, you can try drawing the pictu...

How To: Find the surface area of a pyramid with BabelMath

A pyramid is a three dimensional figure with the base in the form of a triangle and three slant sides to it. To find the surface area of a pyramid you have to find the area of the different pieces that make it up. The pyramid base can be triangle or even other geometric figure like pentagon. So first draw the base of the pyramid separately and compute its area first. Now compute the area of each sides separately. The area of each side can be same if the pyramid is a regular pyramid. Some time...
