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...
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....
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...
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...

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...
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...

The video shows us how to find the area of parallelogram using geometry. Here in this video it is done by using an example where the parallelogram is given ABCD. The area of the parallelogram is base times height (bh). Here the base is given as 15 but the height is not known but it is represented by the segment BD. To find the value of h, let’s use right triangle BDC on the right side of the figure. Since base is 15 and the opposite side of the parallelogram is congruent, the hypotenuse of th...
Free Math Tutoring teaches you in this video how to calculate the area of a triangle using a basic formula. The area of a triangle is (b times h)/2. B is the base of the triangle and h is the height. This formula works for all kinds of triangles. Sometimes you won't have the height in the triangle, so you need to draw a line from one angle to the base opposite that, at a 90 degree angle. Measure that and you have your height. It might seem difficult at first, but practice helps you understand...

Then the piezoelectric sensor, held in a small adjustable clip, is heated briefly, and two drops of solder placed where the wires are to be attached. Finally, the tinned ends of the wires are placed in contact with the soldered areas of the piezoelectric sensor, and the solder heated to fix the wires in place.
