Little one at school starting to learn shapes? Mother, don’t forget to introduce the shape of the room, okay? The material for building space is one of the teaching materials for Mathematics.
According to Nur Lailah Indah Sari in the book The Fun of Learning to Build a Flat Side Room, Building space is a threedimensional building that has volume or content.
A wake has six parts, namely:
 Side plane, namely the field / side that limits between one space and another.
 Rib, which is the meeting of two sides on a flat shape that appears as a line segment.
 Corner point, which is the point where two or more edges meet in a shape.
 Side diagonal, which is the diagonal line from the side of the building.
 Diagonal plane, which is the flat plane of the side and edge diagonals.
 Space diagonal, which is a diagonal line from a diagonal plane.

Build a space divided into two, build a flat side room and build a curved side room. Come on, see the explanation below.

Building a flat side space according to Nur Lailah Indah Sari is a space that has a flat side, not a curved side. There are four types of flatsided shapes, namely cubes, blocks, prisms, and pyramids.
1. Cube
A cube is a shape in which all sides are square and have sides that are the same length. The characteristics of the cube include:
 It has six squareshaped areas.
 It has eight vertices and all angles are right angles or 90 degrees.
 It has 12 sides of the same length, 12 side diagonals, and 4 space diagonals of the same length.
The formula for calculating the volume of a cube is the area of the base x height or s3 where s is the length of the side of the cube.
To introduce your little one to cubes, there are some everyday items that you can use as examples. One of them is dice.
2. Block
Beams according to Drs. Joko Untoro in the book Math Genius is a form of space bounded by six rectangular fields and pairs of equal and congruent. The characteristics of the beam include:
 Has 12 ribs, six sides, and eight corner points.
 Has eight vertices and all angles are right angles or 90 degrees
 Formed from four rectangular sides facing each other in pairs and two square sides facing each other.
The volume of the block is calculated by the formula length x width x height. Examples of blocks that you can show your little one are wardrobes, shoe boxes, and refrigerators.
3. Triangular prism
Prism is a form of space bounded by two parallel planes, these two parallel planes are the base plane and the lid plane. The base and lid of a prism are generally triangular and are known as triangular upright prisms. A triangular prism has nine edges, five sides and six vertices.
To calculate the volume of a triangular prism, use the formula for area of base x height. The base of a triangle can be calculated by the formula x base x height. Mother can show the tent to the Little One to introduce him to a triangular upright prism.
4. Limas
Pyramid is a shape that is limited by a facet as a base plane and several vertical planes in the form of a triangle. There are two types of pyramids, namely triangular pyramids and rectangular pyramids.
A triangular pyramid has a triangular base with six edges, four sides, and four vertices. Meanwhile, a quadrilateral pyramid has a quadrilateral base with eight edges, five sides, and five vertices.
The volume of the pyramid depends on the base of the triangle or quadrilateral. The pyramid can be calculated as x area of the base x height. If the base is a triangle, the area of the base is calculated by the formula x base x height. If the base is a quadrilateral, the area is calculated using the formula length x width.
An example that Mother can give for the Little One is the Egyptian Pyramid which is shaped like a square pyramid.
Build a curved side room

Building a curved side room is a room that has a blanket and has a curved part. There are three types of plane shapes, namely cylinders, cones and spheres.
1. Fund
In the book Math Genius, tube or cylinder is a form of space bounded by two circles that function as a base and a lid. The tube has three sides, namely the base, lid, and blanket and has two ribs. The tube is also a shape that has no corner points.
The formula for calculating the volume of a cylinder is area of base x height. Calculate the area of the base of the cylinder using the area of the circle. Therefore, the formula for calculating the volume of a cylinder is 2x phi x r2 x t.
Examples of tubes in everyday items that you can show your little one are cans, water pipes, and water hoses.
2. Cones
Similar, but not the same, cones have a shape similar to that of a pyramid. However, the base of a cone is a circle, unlike a pyramid with a square base. The cone has two sides, namely the base and the blanket and has one rib. In addition to the tube, the cone is also a geometric figure that has no vertices.
The volume of a cone is calculated by the formula for area of base x height with a circle as the base. Examples of cones that you can show your little ones are birthday hats and cone it crimea.
3. She was
Another curved side space is a sphere. Your little one must be familiar with the ball. Build this one room only has one side and has no corner. The volume of the sphere can be calculated by the formula phi x r3.
Mothers can show various kinds of balls to your little one, for example pingpong balls, basketballs, soccer balls, to tennis balls.
Thus the explanation of the problem of building space in mathematics. Hopefully useful, Mother.
