Depends on the textbook. For example, my math book is only about five inches, but my Geography book on the other hand is twice the size. Overall, it's the subject and authors that really factor in.
The area of a rectangle is given by the formula: length x width. So, for the textbook, the area would be 5cm x 2cm = 10 square cm.
volume
It depends on the book!
if you meant width then a computer if you meant thickness a since textbook i you meant length then a textbook
The best unit for measuring the width of a textbook would likely be centimeters (cm) or inches (in), as these are commonly used units of measurement for smaller objects like books. These units provide a precise measurement that is easy to understand and compare.
appropriate unit to measure the width of a textbook = ce ntimeters
perimeter = length + length + width + width = 2*length + 2*width = 36 length = 5*width 2*(5*width) + 2*width = 36 12*width = 36 width = 3 length = 15
The volume of a math textbook would depend on its physical dimensions. It can be calculated by multiplying the length, width, and height of the textbook. A common unit for volume is cubic inches or cubic centimeters.
Area = length x width Length = area/width
Length / Width
Length and width
If Length * Width = Area, then Area ÷ width = Length
