No. A smooth brick, for example, is a cuboid with no squares.
Yes, all cubes are cuboids because a cuboid is defined as a three-dimensional shape with six rectangular faces, and a cube meets this criterion with all its faces being equal squares. Therefore, while all cubes are cuboids, not all cuboids are cubes, as cuboids can have faces of different dimensions.
Cuboids are not always similar.
Cubes and cuboids are both three-dimensional geometric shapes that have length, width, and height. They share the property of having six faces, all of which are rectangular in shape; in the case of cubes, all six faces are squares. Additionally, both shapes have vertices and edges, with cubes having 8 vertices and 12 edges, while cuboids may have different dimensions but still maintain the same number of vertices and edges.

No.First of all, you can't write negative numbers as sums of perfect squares at all - since all perfect squares are positive.Second, for natural numbers (1, 2, 3...) you may need up to 4 perfect squares: http://en.wikipedia.org/wiki/Lagrange's_four-square_theoremNo.First of all, you can't write negative numbers as sums of perfect squares at all - since all perfect squares are positive.Second, for natural numbers (1, 2, 3...) you may need up to 4 perfect squares: http://en.wikipedia.org/wiki/Lagrange's_four-square_theoremNo.First of all, you can't write negative numbers as sums of perfect squares at all - since all perfect squares are positive.Second, for natural numbers (1, 2, 3...) you may need up to 4 perfect squares: http://en.wikipedia.org/wiki/Lagrange's_four-square_theoremNo.First of all, you can't write negative numbers as sums of perfect squares at all - since all perfect squares are positive.Second, for natural numbers (1, 2, 3...) you may need up to 4 perfect squares: http://en.wikipedia.org/wiki/Lagrange's_four-square_theorem

There are 5 squares in a 2 by 2 grid if the large square enclosing all four smaller squares is included in the count.
That would obviously depend on how big you want your cuboids.

The characteristics for a rectangle is that it has to have 4 right angles and 2 pairs of congruent and parallel sides. Squares have to meet these requirements and also have to have all sides congruent. All rectangles meet to the rectangle's standard, but not all of them meet up to a square's standard. Therefore, not all rectangles are squares. Or, in a more simplified version: squares are a type of rectangle, but rectangles are not a type of squares, therefore not all rectangles are squares.
They can't, unless you're cutting them all into different sizes.
Yes, all Squares are rectangles, but not all rectangles are squares because it needs to have all equal sides.
No, rectangles are not squares
you press all the squares on the second row once then the 2 in the middle on the third row then all on the last row
Yes, all squares are rhombi (aka rhombuses), but all rhombi are not squares.
A cuboid has 8 vertices so 5 cuboids have 5*8 = 40 vertices.
