Satish purchased Sugar Cube having length 3cm. Find value of cube.
Answers
Step-by-step explanation:
A cube is a solid box whose every surface is a square of same area.
Take an empty box with open top in the shape of a cube whose each edge is 2 cm. Now fit cubes of edges 1 cm in it. From the figure it is clear that 8 such cubes will fit in it. So the volume of the box will be equal to the volume of 8 unit cubes together.
Therefore, the volume of the cube = 8 cu cm
Note that 8 = 2 × 2 × 2
Thus, volume of a cube = side × side × side = side3
Hence, a cube has:
(i) six surfaces or faces,
(ii) 8 vertices,
(iii) 12 edges or sides of equal length.
Cube
Since a cube has all sides equal.
Volume of a cube = (side × side × side) cubic units.
= 1 × 1 × 1 cubic units
Since area = side × side
Volume of a cube = (area × side) cubic units.
