To find: the dimensions of the mold.
Answer to Problem 3PS
The side of the square base is 2 and the height is
Explanation of Solution
Given information:
At a glassware factory, molten cobalt glass is poured into molds to make paperweights. Each mold is a rectangular prism whose height is 3 inches greater than the length of each side of the square base. A machine pours 20 cubic inches of liquid glass into each mold.
Calculation:
Assume that the length of the side of the square is
Now, find the value of
By hit and trail method we can see that 2 is the root of the equation.
So
Factorize it as follows,
The quadratic have no real root.
To check this we can check the discriminate which is negative.
So 2 is the only real root.
So, the side of the square base is 2 and the height is
