# Cubes

Cubes in maths is a Solid geometrical shape, whose all sides are of equal length means length, width and height of cubes are of equal length. All sided (length, height and width) of cubes are defined in 3d (3 dimension), that’s why we call this solid Geometry as a cubes in 3d. Now we discuss geometry of cube.

Each Cube made by 6 squares which meet at right angles means if we connect 6 squares at right angles, then produced geometry is known as cube geometry and each cube has 8 vertices and 12 edges. So, cube is a 3d geometry.

Now we discuss formulas for calculating volume and surface area of cubes:
Volume of cubes = a * a * a,
Here ‘a’ is length of cube, ‘a’ is height of cube and a is width of cube,

Surface area of cubes = 6 * a2,
Here ‘a’ is length of cube, ‘a’ is height of cube and ‘a’ is width of cube,

Suppose, we have a cube, whose length, height and width is equal to 5 inch, then–
Volume of cube = a * a * a,
= 5 * 5 * 5,
= 125 inch3.
Surface area of cube = 6 * a2,
= 6 * (5)2,
= 6 * 25,
= 150 inch2.
So, volume of cube is 125 inch3 and Surface Area of Cube is 150 inch2, where length, height and width are equals to 5 inch.

All three sides length, width and height of cubes are define in 3 d geometry like here in above example length, width and height of cubes are 5 inch are define in 3 dimension and volume of given cube is 125 inch3 and surface area of this 3d solid geometry, which is called as a cube is 150 inch2.
This is all about 3d cube geometry.

## Surface Area of Cube

Cube can be defined as a 3 dimensional object, which consists of 6 faces and each face has equal dimensions or we can also say that Cube consists of 6 squares of equal dimensions or sides.

Let us now see what is Surface Area Of Cube, it can be as combined area of all the faces of the cube or combined area of all 6 Square faces.

Area of one face of a cube is gi...Read More

## Volume of Cube

In Geometry we study about the different figures, two dimensional and three dimensional.  For three dimensional figures, we need to learn about the capacity (which we call the volume) and the surface areas of the different shapes. Here we will study about volume of Cube. A cube is the three dimensional figure, which we say has 6 faces, and each face of which is in the for...Read More
