4 of these dimensions are the regular ones most of us are familiar with; 3 of these are spatial dimensions: up-down, left-right and forwards-backwards. The fourth one is a time dimension.
In a 4 dimensional space you thus require four numbers to uniquely specify a certain location in space and time. A quick example would be the location of a meeting somewhere on Earth; you'd need four bits of information: the latitude and longitude of the location, the height and finally the time of the meeting.
In M-theory physicists assume there are 7 additional spatial dimensions. Thus in M-theory you would need a grand total of 11 numbers to uniquely specify a location in spacetime.
These additional 7 dimension are not equal to the regular 3 spatial dimensions in one important aspect; they are curled into small loops. This makes them periodic (if you walk in their direction you will after a while end up where you started), and they are very tiny. You can imagine them as small loops of additional space at every location in our regular 4 dimensional spacetime.
These loops cannot be seen however because they are so very tiny. If M-theory is correct we might be travelling in these dimensions all the time, but we don't notice it because they are so small.
A good analogy Briane Greene used is that of an ant on a garden hose. For the ant the garden hose seems 2 dimensional (3 if you count time); the ant can move forward and backwards on the hose, but it can also move around along the hose in a circular fashion. But if you stand some distance away the hose appears to be a line, a 1-dimensional object. You do not see the second curled-up dimension because it is too small because you are too far away.
In this way the extra dimensions M-theory requires are also hidden, but they might be spotted in modern particle collider experiments such as the LHC, since these can be used to probe the small distance scales where these additional dimensions might become important.
There are as many as eight or nine dimensions. The fifth dimension is (mass or weight) in essence contact. However this negates Time position as the fourth dimension RELATIVE to distance. GO ALIENS!
Yes, according to current scientific theories, there are more than 3 dimensions in the universe. Some theories suggest there may be up to 11 dimensions, with the extra dimensions beyond the familiar three spatial dimensions and one time dimension being compactified or hidden from our everyday perception.
In spacetime, there are four dimensions: - Height - Width - Depth - Time I'm not sure what the fifth dimension might be, I think M-Theory or String Theory takes it all the way up to 11 dimensions, but I'm guessing that's not what you're after.
In classical Newtonian physics, there are three spatial dimensions (length, width, and height) and one time dimension, making a total of four dimensions. In some advanced theories such as string theory or M-theory, it is proposed that there may be additional spatial dimensions beyond the four we perceive in our everyday experience.
Einstein formulated the spacetime that is the four dimensions of space namely: length, breadth, thickness and a fourth dimension: time are interwoven. apart from euclid's geometry where time is said to move at a constant rate and is unchangable, this theory says that time also can be bent, slowed down or even speeded up just like the other dimensions like length.

A standard birth certificate is typically 8.5 inches by 11 inches in size, which is the same size as a regular sheet of paper.
121 out of 11 in lowest terms is 11/1 or 11
11% in lowest terms is 11/100
Standard bicycle sprocket dimensions typically range from 11 to 34 teeth, with common sizes being 11-28, 11-32, and 11-34. These dimensions refer to the number of teeth on the sprocket, which affects the gear ratio and overall performance of the bike.
How about: 11, 11, and 3 cm or as 7, 7 and 11 cm for its perimeter dimensions
The volume of a suitcase with the dimensions of 15 inches x 14 inches x 11 inches is 2310 inches3.
There are as many as eight or nine dimensions. The fifth dimension is (mass or weight) in essence contact. However this negates Time position as the fourth dimension RELATIVE to distance. GO ALIENS!
The dimensions are: Length = 18 feet Width = 11 feet Height = 8 feet
11/45 is already a fraction in its lowest terms.
11 millimeters = 0.43 inches in any terms.
