The answer depends on the metric that is used for measuring distance. For most metrics the 3-d formula is simply the extension of the 2-d version. For example, the Pythagorean formula, for the distance between X = (a,b,c) and Y = (d,e,f) is
distance = sqrt[(d-a)2 + (e-b)2 + (c-f)2]
Since speed or velocity = distance/time ,its dimensional formula =L/T = [MoLT-1]
three dimention
Three, of course!
How i can know a bearing number from bearing dimension.
[p]=[wl-1]
what is the formula for finding a 3 dimensional square
The dimension of power is (energy / time)= (force x distance) / time= (mass x distance / time2) x distance / time= mass x distance2 / time3= ML2T-3
what are the quaities of a painting without depth or the illusion of three dimension
An "other dimension" is a dimension other than the three dimensions of space and one of time that we normally experience.
volume
it is a pure number and has no dimension
The Fourth dimension in Space is a real distance dimension r, completing the three vector displacement dimensions. Space is a quaternion with one real dimension and three vector dimensions, s= r + Ix + Jy + Kz, where I,J and K denote the vector dimensions. The real dimension r is related to time by r=ct where c is the speed of light. Einstein and Minkowski proposed in Relativity Theory a defective four dimension Space, where the fourth dimension is a vector Ict . This Space is essentially a two dimensional Space and does not exhibit the non-commuttive features of the quaternion Space.
