Explanation

Number of heads = 48

Number of feet = 140

Calculation:

Let the number of hens is x and the number of cows is y. Therefore,

x + y = 48           ----(1)

According to the question,

2x + 4y = 140

⇒ x + 2y = 70     ----(2)

Subtracting (1) from (2), we get

y = 22

Put this value in equation (1)

⇒ x = 48 - 22 = 26

No.of hens =26
No. of cows =22.

Explanation

If each side of the cube is doubled in length, the new side length will be twice the original side length. Since the volume of a cube is proportional to the cube of the side length, the new volume will be:

New volume = (2 × original side length)^3

Since the original volume is 8 cubic meters, we can find the original side length by taking the cube root of 8:

Original side length = ∛8 = 2 meters

Now, we can find the new volume:

New volume = (2 × 2)^3 = (4)^3 = 64 cubic meters

So, the correct answer is: 64
