Answer:
Because there are many different ways to teach introductory astronomy, we have made the text as flexible as we could. Math examples are shown in separate sections throughout, so that you can leave out the math or require it as you deem best. Each section of a chapter treats a different aspect of the topic being covered; a number of sections could be omitted in shorter overview courses and can be included where you need more depth. And, as we have already discussed, you can customize the book in a variety of ways that have never been possible in traditional textbooks.
Step-by-step explanation:
This book is written to help students understand the big picture rather than get lost in random factoids to memorize. The language is accessible and inviting.

Each chapter contains interactive group activities you can assign to help students work in teams and pool their knowledge.

SOLUTION:
Let the width of cardboard be
length of cardboard
As box is formed by cutting squares from corners of cardboard
length of cardboard
width of cardboard
height of cardboard
volume of cardboard
solving we get
