How to Calculate Volume of a Box
Whether you need to mail a package or pass you next test, finding the volume of a box is easy. Volume is the measure of how big an object is in three dimensions, so the volume of a box measure how much room there is inside of the box. To find it, you need to make a few simple measurements of length, width, and height, and then multiply them.
Calculating the Volume of Rectangular Boxes
Understand the volume of a rectangle equals it'slengthxwidthxheight.If your box is a rectangular prism or a cube, the only information you need is the box's length, width, and height. You can then multiply them together to get volume. This formula is often abbreviated asV = l x w x h.
- Sample Question:"If I have a box with a length of 10cm, width of 4cm, and height of 5cm, what is the volume of the box?"
- V = l x w x h
- V = 10cm x 4cm x 5cm
- V = 200cm3
- "Height" may be replaced with "depth." For example, "The box has a length of 10cm, width of 4cm, and is 5cmdeep."
Measure the length of a box.If your are looking down at your box, the top appears to be a flat rectangle/The length the longest side of this rectangle. Write this number down as "length."
- Make sure you use the same measurement for each side -- if you measure one side in inches, you need to measure them all in inches.
Measure the width of the box next to the length.The width of the box is the other edge next to the length. If you are looking one side of the box, the width is the side the forms an "L" with the length. Write down this measurement as "width."
- The width is always the shorter side.
Measure the height of the box.This is the last side you have not measured, and is the distance from the top of the box to the ground. Write this measurement down as "height."
- Depending on how the box is laying, which side you call "height" or "length" might be different. However, it doesn't matter what side you call the length, just that you measure 3 different sides.
Multiply the three sides together.Remember, the equation for volume isV = length x width x height, so simply multiply all three sides together to get your volume. Be sure to include the units you used to measure with as well, so you don't forget what your numbers mean.
Add the "units3" to your volume.Volume is a measurement, but if you don't know what the measuring system your number will be meaningless. The correct way write out volume is with your type of measurementcubed. For example, if I measured all the sides in inches, my final answer would be in "inches3." For example.
- Sample Question:"If I have a box with a length of 2 feet, width of 1 foot, and height of 3 feet what is the volume of the box?"
- V = l x w x h
- V = 2ft x 1ft x 4ft
- Volume = 8ft3
- Advanced Note:'This is because volume tell you how many small cubes you could fit in the box. In the previous example, this means we could fit eight separate 1 foot cubes in our box.
Calculating Different Shaped Boxes
Find the volume of cylinders.Cylinders are tubes, where the top and bottom are circles. To find volume of a cylinder, use the equation V = pi x r2x h. Where pi = 3.14, r is the radius of the top circle, and h is the height.
- To find the volume of a cone, or pyramid with a circle for the bottom, use the same equation time 1/3. So, Volume of a Cone = 1/3(pi x r2x h)
Find the volume of a pyramid.Pyramids have one side, or base, and all of the other sides comes to a point. To find volume, multiply the area the base by the height, and then multiply that by the fraction 1/3. Thus, Volume of a Pyramid = 1/3(base x height).
- Most pyramids have square or rectangular bases. The area of a base is found by multiplying the length of the base by the width.
Add the volume of the parts together to find the volume of complicated shapes.For example, if I need to find the volume of an "L" shaped box, there are more than three sides to measure. If you view the box as two smaller boxes, however, you can find the volume of each smaller box and add them together to get the final volume. With our "L" shaped box, for example, we can view the vertical line as a rectangular box and the bottom horizontal line as a square box.
QuestionI got 26 boxes of flooring; each box has 14 square feet in it. The length of my floor is 357 inches, the width is 142 inches. Do I have enough to cover floor?Top Answerer26 x 14 = 364 square feet of flooring material. 357 x 142 = 50,694 square inches. Divide by 144 to get 352.04 square feet. Theoretically you do have enough flooring, but with waste, it would be close!Thanks!
QuestionHow do I find the length, width, and height if I'm given the total amount?Top AnswererIf that's all you're given, you can't find the other numbers.Thanks!
QuestionHow do I find the volume of a box in cubic feet?wikiHow ContributorCommunity AnswerConvert any measurements you have into feet, then find the volume of a box in cubic feet the same way you would for any other unit of measurement.Thanks!
QuestionIs it possible to find the volume of a rectangular prism without the depth?Top AnswererNo. The volume is calculated by multiplying the depth (height) by the area of the base.Thanks!
QuestionHow do I tell how many bottles I can put on a tray?Top AnswererAssuming identical, cylindrical bottles and a square or rectangular tray: Divide the diameter of a bottle into the length of the tray. That's how many bottles you can fit in one direction. Divide the diameter into the width of the tray. That's how many bottles you can fit in the other direction. Multiply the two numbers together to get the total number of bottles that will fit.Thanks!
QuestionHow do I calculate centimeters squared into grams?Top AnswererOne does not convert to the other. Cm² is a unit of volume. Gram is a unit of weight.Thanks!
QuestionHow do I calculate the height of a cuboid?wikiHow ContributorCommunity AnswerDivide the width by the height.Thanks!
QuestionHow do I change total volume to square feet?wikiHow ContributorCommunity AnswerYou can't.Thanks!
Question6912 cubic inches equals how many gallons?Top AnswererMultiply by 0.004329.Thanks!
QuestionTo find the volume of a box, you can multiply its height, width, and length. The measure of the volume of a box is 70. What are its possible dimensions?Top AnswererThere are literally an infinite number of possibilities. One possibility is 7 x 5 x 2.Thanks!
If the dimensions of a box are 31x31x23 cm, weight 3 Kg, and there are 6 boxes, will the volume be (31x31x23)x6?
