About Cube A cube is a three-dimensional solid object bounded by six square faces, facets or sides, with three meeting at each vertex. The cube can also be called a regular hexahedron and is one of the five Platonic solids. It is a special kind of square prism, of rectangular parallelepiped and of trigonal trapezohedron. Kubus adalah bangun ruang tiga dimensi yang dibatasi oleh enam bidang sisi yang berbentuk bujur sangkar. Kubus memiliki 6 sisi, 12 rusuk dan 8 titik sudut. Kubus juga disebut bidang enam beraturan, selain itu juga merupakan bentuk khusus dalam prisma segiempat. Loading… TRANSLATE

Edges of Cube AD adalah rusuk (AD is edge) DC adalah rusuk (DC is edge) CB adalah rusuk (CB is edge) BA adalah rusuk (BA is edge) And so on A B C D E F G H Edges of Cube

Faces of Cube ABCD adalah sisi (ABCD is face) EFGH adalah sisi (EFGH is face) And so on Faces of Cube A B C D E F G H

Diagonal of Faces BE adalah diagonal sisi (BE is diagonal of faces) AF adalah diagonal sisi (AF is diagonal of faces) And so on A B C D E F G H Diagonal of Faces

Diagonal of Cube BF adalah diagonal ruang (BF is diagonal of cube) GC adalah diagonal ruang (GC is diagonal of cube) And so on A B C D E F G H Diagonal of Cube

Formulas of Cube Volume = s3 5 cm 5 cm 5 cm So, the volume of water is = 5 x 5 x 5 = 125 cm3

Formulas of Cube Surface Area of Cube= 6s2 3 cm 1 3 cm 2 3 4 5 Area of square = 3 x 3 = 9 cm2 6 Surface Area of Cube = 9 x 6 = 54 cm2

Formulas of Cube Diagonal of Face = a√2 5 cm x x2 = 52 + 52

Formulas of Cube Diagonal of Cube = a √3 Note : Blue line = diagonal of cube 4 cm Formulas of Cube x2 = 42 + (4 2 )2 x2 = 16 + 32 x2 = 48 x = 48 x = 4 3 x 4 2 cm

Area of the diagonal of plane= edge x diagonal of face Perimeter of the diagonal of a plane= 2(edge) + 2(diagonal) 4 cm Formulas of Cube 4 2 cm Area of diagonal of plane= 4 x 4 2 = 16 2 The perimeter = 2(4) + 2(4 2 ) = 8 + 8 2 = 8(1 + 2 )
