As you have probably noticed, there are an infinite number of pyramids: ones with quadrilateral bases, pentagon bases, hexagon bases, septigon bases...  The more sides the base has, the closer the pyramid will come to a cone.\n\nYes, a square pyramid has a base of a square.\n\nI guess the common property is that they all have triangular sides.

square pyramid...if square as base\n\ntriangular pyramid...if triangle as base\n\nBasically just look at the base...and add pyramid to it.\n\nEx. 5 sided regular polygon base...pentagonal pyramid.\n\nIf it isn't a regular polygon...look it up...or just leave it as pyramid I guess. LOL!\n\nTetrahedron...sound molecular...like the shape of methane molecule. I'm thinkin' this is geometry...so stick with the simplistic "pyramid".\n\nOH...BTW...if it only has one base...and is composed of multiple triangular sides...then it's a pyramid. If it has 2 bases...and any other figure for it's sides...then it's a prism.

some confusion as to whether the phrase "the cube of" also applies to "the second part" ot not

A four-dimensional hypercube.   If you consider time as a fourth dimension, a tesseract would be a cube which has sides of, say 1 metre, suddenly appears, exists for the time equivalent of 1 metre, that's the time it takes light to travel 1 metre, which is 1/ 300 000 000  second,then vanishes.

A is the answer.  The other answers doesn't make sense at all.\nI just learned this stuff 3 years ago!

First of all, I'm assuming, since the dimensions you gave for the rectangles don't go above three units in any direction, that the cube is 3x3x3.\n\nPicture a slice of the cube which is 1x1x3.  Then you can have two 1x1x2 rectangles within it facing in the same direction.  There are nine of these slices in the cube which point in that direction, and 18 of the 1x1x2 prisms.  There are three equivalent directions to point in, so there are a total of (3x9 =) 27 1x1x3 prisms and (3x18 =) 54 1x1x2 prisms.  (Incidentally, you forgot to mention 1x1x3 in your list.)\n\nNow picture a slice of the cube which is 1x3x3.  Within this slice there are four 1x2x2 slices and four 1x2x3.  Three large slices make up a cube, so in any given direction, there are three 1x3x3 and twelve each of 1x2x2 and 1x2x3.  Again, the slices can go in any direction, so there are a total of nine 1x3x3 rectangles and 36 each of 1x2x2 and 1x2x3.\n\nFor 2x2x3, they can point in any of the three directions and go all the way through the cube in that direction.  in the plane of the other two directions, their cross section is a 2x2 square, which can have four positions within a 3x3 square.  So there's four of these in each direction, or 12 total.\n\nFor 2x3x3, you're basically just removing a face of the cube.  There are six faces, therefore six 2x3x3 rectangles.\n\nTo recap:\n\n1x1x2: 54\n1x1x3: 27\n1x2x2: 36\n1x2x3: 36\n1x3x3: 09\n2x2x3: 12\n2x3x3: 06\n\nTotal: 180

umm...do you mean slant??\n\nvertical, horizontal, and slant should be it.

The answer is either b or c.\nI recall that this is the gametophyte generation. I'll go with (b) because I also recall that it was a heart shaped structure.

Storage_ I corrected a miscount.\n\nThe answer is 12+24 = 36\n\nPlanes that include 4 vertices = 12\n\nobviously the six faces = 6\nPlanes that pass through the two parallel diagonals of opposing faces. There are two of these for each face but since they join two opposing faces there are 2*3 = 6\n\n24 planes that include only 3 vertices\nFor each face of the cube there are two diagonals and each digonal belongs to two planes that pass through the two vertices which are kitty corner to the end-points of the diagonals. this gives 2*2*6 =24

1.Two\n2.non-collinear\n3.non-planer\n4.collinear\n5.Parallel\n\nthere can be another word for (3) but it is also correct
