There is only one three digit number for a gross, and that is 144.
The only three-digit number that fits the criteria of being a square number and having a product of its digits equal to two is 128. This is because 128 is a square number (11^2 = 121, 12^2 = 144) and the product of its digits (1 x 2 x 8) equals 16, which is not equal to two. Therefore, there is no three-digit number that meets all the given conditions.
Nothing in this universe: 16,25,36,49,64 & 81 are the only 2-digit squares.
To be both, a cube and a square, the number would have to be a 6th power. 26 = 64 is too small 46 = 4096 is too large So the only possibility is 36 = 729
