Question

Several identical cubes are arranged in a close-packed single layer. If the area of the layer is A and the volume of the layer is V, then the number of cubes in the collection is
1. V/A.
2. A3/V2.
3. V2/A3.
4. A/V.

Answer 1

Step-by-step explanation:

side is v/A

area= v^2/A^2

total number of cubes= area of the layer/ area of each cube = A^3/V^2
