A square-based prism, a square-based pyramid and a cube.
No. One yard is three feet. One square yard is three feet on each of 4 sides. One square foot is a foot on each of four sides. One square yards has 3 times the area of one square foot.
hmmm... square triangle. uh 3 and a half? If you mean a right triangle with a square angle then it would be 3 All triangles have three sides and three angles. Tri(three)angle, see?
3 inches, because the square root of nine is three
A pentagon has fives sides, or if you mean a three dimensional shape, a pyramid has five sides, four triangular and one square.
If a square's area is 10 square feet, the length of one of its sides is 3.16227766 feet.
congruent means that all the sides are the same length. the sides of a square have to be the same length or else it would be a rectangle. Not all triangles are congruent though. there are other types of triangles unlike the square, where there is only one type.
4 sides
Polynomials have terms, but not sides. One with exactly three terms is a "trinomial". Polygons have sides. One of those with exactly three sides is a "triangle".
Such a figure is called a square. Actually only one right angle is enough to force the the other angles to be right, and if three sides are equal, that forces all sides in such a figure to be equal. Exercise: Prove that any 4-sided figure( called a quadrilateral in math books) with three equal sides and one right angle is a square.
A square is two-dimensional and occupies one plane. A cube is three-dimensional and contains 6 planes, and 3 pairs of parallel sides.
yes, and a square has to have 2 parallel sides to be a square.
multiply one of the longest sides by one of the shorter sides or if a square just multiply 2 sides
