Understanding how to calculate volume is crucial for accurately determining the amount of space an object occupies or the quantity of a given substance. In conclusion, calculating volume plays a vital role in various fields, including mathematics, engineering, architecture, and science. Follow the steps below to see if you can spot the similarities! You may find that the formulas for volume have the same parts that you can use to remember them. X Research Resources This article will show you how to calculate the volume of 6 three-dimensional cubes commonly encountered in math tests, including cube, rectangle, cylinder, pyramid, conical and spherical. Common units of volume include cubic centimeters (cm 3 ), cubic meters (m 3 ), cubic inches (in 3 ), and cubic feet (ft 3 ). X Research Source You can also imagine the volume of a shape as the amount of water (or air, or sand, etc.) that the shape can hold when filled with the above objects. The volume of a shape is a value that indicates how much of a three-dimensional space the shape occupies. For example, if the circumference you get after 3 measurements is 18 inches, 17.75 inches, and 18.2 inches, add these values together (18 + 17.5 + 18.2 = 53.95) ) and divide the total found by 3 (53.95/3 = 17.98).Measuring a sphere can take some ingenuity, so to get the most accurate results possible, you should measure 3 times and then average the value (add the value obtained after 3 measurements).For example, if you measure a ball and get the circumference of the ball to be 18 inches, divide that number by 6.28 and you get the value of the radius to be 2.87 in.Divide this value by 2π, or 6.28, to get the radius of the sphere. Use a ruler to measure the length of the string to get the circumference. Then use this piece of string to wrap around the sphere at the widest part and mark the intersection of the string. If you need to measure a sphere (like a tennis ball) to find the radius, first find a piece of string long enough to wrap around the sphere. Measure the radius if this value is not known. The circumferential method will usually give more accurate results. If you want to find the really exact value of the circumference, you can apply and compare the results obtained from the two methods above, if the results are significantly different, check again.For example, if the circumference you measured was 8 inches, the radius would be 1.27 in.Divide the circumference by 2π (or 6.28) and you will find the value of the radius. Once you get the circumference, you apply the following formula: C(Perimeter) = 2πr.
