Pooja writes the ratio x/3 = y/4 to help her increase the size of the two dimensional shape. New volume of x is 15 units. What is the value of y?

To find the value of y, first we need to solve for x using the given information.

If x/3 = y/4, we can cross multiply to get:
4x = 3y
Now we know that x has a volume of 15 units, so:
4(15) = 3y
60 = 3y
y = 20

Therefore, the value of y is 20.
