Question

The perimeter of one face of a cube is 40 cm. The volume of the cube (in cm3) is
(a) 1600
(b) 1000
(C) 800
(d) 160​

Answer 1

Answer:

Let one side of the cube =s.

Then, perimeter of one face of cube =4s.

But given, perimeter of one face of cube =40 cm.

Then,

⟹4s=40 cm

⟹s=10 cm.

∴ Volume of the cube =s

3= 10

3= 1000 cm

.

Thus, option B is correct.
