I think I know what your asking so the answer would be 27/30 and 28/30
A number is a perfect square (or a square number) if its square root is an integer; that is to say, it is the product of an integer with itself. Here, the square root of 20 is about 4.472. Thus, the square root of 20 is not an integer, and therefore 20 is not a square number.
Given:
Volume of the prism = 60 in³
Breadth = 2.5 in
Height = 4 in.
To find:
The length of the prism.
Solution:
We know that, volume of a prism is

where, l is length, b is breadth and h is height.
Putting V=60, b=2.5 and h=4, we get


Divide both sides by 10.


Therefore, the missing dimension of the prism is 6 in.

Have a wonderful day ahead
