Let volume of 4% solution = x and of 14% be y
them x + y = 65........(1) also using the actual weights of salt:-
0.04x + 0.14y = 65*0.06 = 3.9
multiplying the above equation by -25 we have
-x - 3.5y = -97.5 adding this to equation (1)
--2.5y = -32.5
y= 13
and x = 65 - 13 = 52
so we need 13 mls of the 14%, and 52 mls of the 4% solution.
The output is the cute of the input is written as y = x³.

Answer:
Triangular prism, 108
Step-by-step explanation:
First, find its base (6*4/2)
12
Then multiply it by its height
12*9 = 108
It's a triangular prism because it's base is a triangle
4 because you make 6 into a fraction which is 6/1. So, 2/3 x 6/1 = 12/3 = 4
