How to calculate the volume of a CUBOID and a CUBE
The formula of calculating the volume of any rectangular prism, such as a cube, looks like this:
v = l*b*h Where -- l = length b = breadth h = height But if you really have a cube, the length, width, and height are all equal, and the formula looks like this:
v = l*
Where:
l* = the length of any side times itself 3 times, or "cubed".
Measure the radius of the base circle. The radius is the distance going from the center point of the circle to any point on the edge of the circle. Once you have your accurate measurement, write it down on a piece of paper.
Calculate the area of the base circle. This is done by squaring the radius, and multiplying it by pi, which is approximately 22/7. The mathematical equation should look like this: RxRx3.14, where – R= radius
Measure the height of the cylinder. The height is the distance from the two bases' edges. Multiply the area of the base by the height. This is your final answer. The mathematical equation should look like this: AxH=V, where – A= area, H= height, and V=volume
Find the radius. Sometimes, you'll be given the radius, other times you may be given the diameter. If you have the diameter, simply divide it in half. You might also be given the surface area or some other property. Don't worry, just find the formula for that property, set it equal to the value you know is the property, and find the radius from there by solving the equation.
Cube the radius. This is basically multiplying the radius by itself three times, (Radius*Radius*Radius).
Multiply the previous answer by 4/3 .
Multiply the answer by π If you want the exact answer, just write your previous answer followed by the " π " symbol.
Have you ever wondered how much ice cream it would take to fill up a cone? You can calculate the volume mathematically with only a couple simple measurements.
The formula looks like this: v =1/3πr ²h
Where: h = height of the cone r = radius of the circular base of the cone
Measure the radius. Go to the base of the cone, which is a circle. The radius is the distance from the center point of the circle to any point on the outside of the circle.
Calculate the area of the base circle. This is done by squaring the radius and multiplying it by pi (approximately 22/7). The mathematical equation looks like this: π r ² , where – r= radius
Measure the height of the cone. Make sure it's accurate, and in the same units as the radius (inches, centimeters, etc). And then multiply it by the previous answer .
Multiply the area of the base by the height of the cone. Simply take the answer that you've written down, and multiply it by the measurement of the height. The mathematical equation looks like this: π r ²h ,
