This is a cracking question. [I'm assuming that 'integral side lengths' is intended also to mean integral positions. That is to say, the position vectors of the cubes' vertices should consist only of integer components...such that we are effectively drawing our cube in a 3D grid. If this was not a condition, the answer would be infinity.] So then: first, there are 53 = 125 1x1x1 cubes. Then 43 = 64 2x2x2cubes. 33 = 27 3x3x3 cubes. 23 = 8 4x4x4 cubes. And, stunningly, 13 = 1 5x5x5 cube. So far we have 225 cubes. That would not be interesting. But we have only counted the cubes with edges parallel to the edges of the main cube. Suppose there are some more cubes formed by diagonal lines? Since edge lengths and vertex positions both have to be integral, and we are working in 3 dimensions, we are actually looking for Pythagorean quadruples - integer solutions to a2 + b2 + c2 = d2 Up to now we have only used trivial solutions like this: 52 + 02 + 02 = 52 Our edges have only moved in one dimension. We might consider edges that move in two dimensions, using the smallest Pythagorean triple: 32 + 42 + 02 = 52 But diagonal edges of length five are clearly not going to fit. So introduce the third component, and we find this: 12 + 22 + 22 = 32 By using diagonal edges it is possible to constuct a few more valid 3x3x3 cubes. It turns out, I think, that four of these can be formed. So we have 229 cubes in total.
5x5x5 gives us 125 7x7x7 gives us 343 343/125 is 2.744
There would be a 125 cubes in a cube that is 5 units x 5 units x 5 units.
No because cubes do not have opposite sides that are different lengths. Cubes have all equal sides and all equal coners. A cube is not a rectangle.
All I can think of are the 2x2x2, 3x3x3, 4x4x4, 5x5x5, 6x6x6, 7x7x7, there might be a 8x8x8, Pyraminx, Megaminx, Octahedron, Teraminx, and the 1x1x1 :)
They are not generally called seven cubes.

Cubes of digits 1 - 4n3. (nxnxn) 13 = 1, 23 = 8, 33 = 27...1x1x1 = 12x2x2 = 83x3x3 = 274x4x4 = 645x5x5 = 1256x6x6 = 216
Sure cubes can tessellate. It's actually very easy to do so with cubes, as they would all have straight sides of even lengths from any angle.
The total volume of two cubes that each have edge lengths of 5 feet is: 250 cubic feet.
When c = the number that is the dimension of the cube (ex. this time, 7), you can find the number of cubes for any size of cube. c3 - (c - 2)3 So for 7, that is 7x7x7 - (5x5x5) 49x7 - 25x5 343 - 125 218 There are 218 cubies in a 7x7x7 Rubik's cube!
If the number cubes are standard dice cubes, the odds of rolling 3 ones is 1 in 216.
There are 12 squares on 2 cubes
You take the number of cubes on one side multiplayed by the number of sides. for example, in the standard rubik cube there are 9 cubes on each side and 6 sides. 9 times 6 is 54 so there are 54 cubes on a ribik cube
For a rectangle, do the following:1. Count the number of cubes on one side of the retangle.2. Count the number of cubes on an adjacent side (not the opposite side)3. Multiple both numbers together. The result is your answer.
If the surface area is 49 cm2 then the edge lengths are 2.858 cm
The answer is the number of inch cubes used in the construction.
Cube one's volume = 9*9*9 = 729 cubic units. As there are two cubes, their volumes added together = 1458 cubic units.
According to Ramanujan, it's the lowest number that can be expressed in two different ways as the sum of two cubes (the cubes of 12 and 1; the cubes of 10 and 9). It 's the answer.
The cube root of 75 is about 4.217163327 cm which will be the lengths of the sides of the cube.
125 of them.
5x5x5=125 and 3x3x3=27 add them to get the combined volume of 152 in^3
The prime factors of 99 are 3 and 11. Their cubes are 27 and 1331.
There is no limit to the number of cubes which can be arranged on top of a rectangular prism.
