Cuboid material = 8× 6- 1× 1× 4 = 44 (square decimeter)
Cuboid volume =6×2× 1= 12 (cubic decimeter) = 12 (liter).
Extended data:
There are 10 unfolding methods for cutting the face of a cuboid, that is, 10 cutting methods.
Features:
1, a cuboid has six faces. The reverse sides of each group are exactly the same.
2. A cuboid has 12 sides, and four opposite sides are equal in length. According to the length, it can be divided into three groups, each group has four sides.
3. A cuboid has eight vertices. Each vertex connects three edges. The three edges of a cuboid are called length, width and height.
4. Two adjacent sides of a cuboid are perpendicular to each other.
Extended data:
Common solid geometric figures and their properties;
(1) cube:
There are 8 vertices and 6 faces. Each face has the same area (or each face is made up of squares). There are 12 sides, and each side is equal in length. Cube is a special kind of cuboid.
② Cuboid:
There are 8 vertices and 6 faces. Each face consists of a rectangle or a set of opposite squares. There are 12 sides, and the four opposite sides are equal in length.
③ Cylinder:
The upper and lower surfaces are circles of the same size. There is a face called a side. When expanded, it is rectangular, square or parallelogram. There are countless kinds of heights, all of which are of equal length.
④ Cone:
There are 1 vertices, 1 surfaces and a bottom surface. It is fan-shaped when unfolded. Only 1 bar high. A tetrahedron has 1 vertices and six sides.
⑤ Straight triangular prism:
A triangle whose three sides are parallel and whose upper and lower surfaces are parallel and congruent.
6. Ball:
Ball is one of the most common figures in life. For example, basketball and football are balls, and the ball is a geometric body surrounded by curved surfaces.
