Cubic inches are the expression of the volume of a three-dimensional object. For typical square or rectangular areas, multiple the length of each side in inches, according to Math.com.
A three-dimensional object has three sides -- often referred to as the object's length, width and depth. Use a ruler to measure each side in inches.
For a square, all three sides are the same. If a rectangular area has sides of 7 inches, 4 inches and 10 inches, multiply these together. The answer is 280.
The answer of 280 is recorded as 280 cubic inches.
A volume in cubic feet can be converted to imperial gallons by dividing by 0.134 or multiplying by 7.462. A gallon is also a metric unit of measurement, but a different volume than an imperial gallon. To convert cubic feet to a metric gallon, multiply the volume by 8.9544.
Full Answer >A tetrahedron is a three-dimensional object that has four faces, six edges, and four vertices, or points. It can be thought of as a pyramid with a triangular base. Regular tetrahedrons are made of four equilateral triangles.
Full Answer >A three-dimensional object is one that exists in three planes, which typically means it has width, length and depth. The three most common directional dimensions are x, y and z.
Full Answer >The Penrose triangle, also known as the Penrose tribar, is an impossible object, which is a type of optical illusion that tricks the mind into interpreting a two-dimensional object as a three-dimensional object. It was first created in 1934 by the Swedish artist Oscar Reutersvard, but it was popularized in the 1950s by Lionel and Roger Penrose.
