Question

Find the volume of cube whose radius edge is 2 cm.
​

Answer 1

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 = side3

Answer 2

Answer:

8cm³

Step-by-step explanation:

vol = Side³

v = 2³=8

therefore vol is 8cm cube
