Problema Solution
An ope-topped box has a square base and a height of 50 inches. If each bottom edges of the box has a length x inches, find the amount of material needed to construct the box. Write the answer in a factored form.
Answer provided by our tutors
Since the box is open-topped we don't need material for the top.
We need to calculate the area of the box without the top:
x^2 + 4*50*x =x*(x + 200)
The material needed to construct the open-topped box is x*(x + 200) in^2.
