A cubic container is fully filled with 8 000 cm³ of water. If 3 200 cm³ of the water is used, find the height, in cm, of water left in the container.
Answers
Answer:
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 = side3Hence, a cube has:
(i) six surfaces or faces,
(ii) 8 vertices,
(iii) 12 edges or sides of equal length.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.
