There is no shape that has four sides and three corners. Two-dimensional shapes, known as polygons, have an equal number of sides and angles. In addition, none of the common three-dimensional shapes have four sides and three corners.
Know MoreA polygon with three corners is a triangle, which also has three sides. Four-sided polygons are known as quadrilaterals. Examples of quadrilaterals include the square, rectangle and parallelogram. Common three-dimensional shapes include the cube, triangular prism, cone, cylinder and tetrahedron. None of the shapes have three corners, or vertices. Some, such as the cylinder, have no corners. Others, such as the tetrahedron, have four vertices.
Learn MoreA regular shape, also known as a regular polygon, is a shape that has sides that are all equal. If there are sides of differing lengths, these shapes are known as irregular polygons.
Full Answer >To make a four-sided pyramid out of cardboard, simply attach four triangles to the sides of a square, and then fold the triangles up and secure them at the apex. Lay all the pieces out and tape them together, and fold them together as the final step.
Full Answer >In general, a shape with four sides, whether they are equal or not, is called a quadrilateral. Another name for this type of shape is a tetragon.
Full Answer >The formula for the surface area of a cube is 6 * a^{2}, where "a" is equal to the length of any of the sides. The volume can be calculated with the formula a^{3}, where "a" is again equal to the length of a side.
