Just enter edges, height, volume or diagonal. If you want to see some examples, just enter your values above.įor further information, just move the mouse over one of the words below and the corresponding piece of the cuboid gets marked. The diagonal from one corner to the opposite corner has the formula square root of (a²+b²+c²) as we can see by applying Pythagoras twice.Ī cuboid is uniquely determined by three of its lengths. For example the surface consists of six rectangles, pairs of two of them having the same area. Most calculations are very simple and directly be seen from rectangle formulas. A rectangular bedroom with one wall being 15 feet long and the other being 12 feet long is simply 12 x 15 180 square feet. For example, a garden shaped as a rectangle with a length of 10 yards and width of 3 yards has an area of 10 x 3 30 square yards. So we can see there are always 4 edges having the same length. Janes measurements of her pools volume yield the result volume 51.00 +/- 4.49 m3 When she asks her neighbor to guess the volume, he replies '54 cubic meters.' Are the two estimates consistent with each other In order for two values to be consistent within the uncertainties, one should lie within the range of the other. The area of any rectangular place is or surface is its length multiplied by its width. Therefore, a cuboid has rectangles as faces.
In the case of a right circular cylinder (soup can), this becomes V r2h.
To calculate the volume of a cylinder, then, we simply multiply the area of the cross-section by the height of the cylinder: V A h. A cuboid is a solid where all edges are perpendicular on each other. The solid shown in Figure 6.11 is an example of a cylinder with a noncircular base.
