The diagonal can be calculated using the Pythagorean theorem. For other 3D shapes, check Omni's Volume Calculator. Another common shape is a cylinder to find its volume, multiply the height of the cylinder by the area of its base ( × r). To get the perimeter the sum of a and b is multiplied by 2 (because the opposite sides are identical). One of the most popular shapes is a rectangular prism, also known as a box, where you can simply multiply length times width times height to find its volume. The area of a rectangle can easily be calculated by multiplying the length of side a and b. In these situations the tool will just show one of the two possible solutions. Adjacent sides of a rectangle is unequal and opposite sides are parallel to each other. For example, a rectangle with perimeter 10 and area 6 has the sides 2 and 3, but it is unclear if it is a that is 2 and b that is 3 or if it's the other way around. Rectangle is a two dimensional plane or geometric shape with 4 straight sides and 4 right angle (90º) corners. If neither of them are specified there can often be multiple solutions. The tool therefore uses the more neutral naming, a and b. When calculating a rectangle's diagonal, perimeter and area it does not matter which side is the base and which side is the height. The distance between the vertical sides are often called the base, while the distance between the horizontal sides are called the height. Rectangles are often depicted with the longest sides horizontally and the shorter sides vertically. The word rectangle comes from the Latin word rectangulus, a combination of rectus (right) and angulus (angle), which refers to the rectangle's four right angles (90°). The volume in SI is a cubic meter, denoted by m3, defined by the volume of a cube whose. If all the sides of a rectangle have the same length it's usually called a square instead. 3 Find the length of the rectangular solid. A rectangle is a geometric shape with four sides where all angles are 90°.
