To find:
a. To expresses the Volume of a box as a function of length of the side of the square cut from each corner of a square cardboard.
Answer to Problem 25AYU
Solution:
a.
Explanation of Solution
Given:
“An open box with a square base is made from a square piece of cardboard of 24” on a side by cutting out a square from each corner and folding the sides.
Calculation:
a. To expresses the Volume of a box as a function of length of the side of the square cut from each corner of a square cardboard.
The following figure describes the problem:
Let represent the side of the square that is cut from each corner of the cardboard.
Let represent the side of the box.
Let represent the height of the box.
The volume of the box .
From the figure, and .
Hence, the volume .
