Question

Estimate the number of words in your textbook, without using a calculator.(The book has about 500 pages, with an average of 38 lines on a page, 12 words on a line.)

Answer 1

`500\ Pages = 228000`

Explanation:

Given

`Pages = 500`

`Lines = 38`

`Words = 12`

Required

Determine the number of words in the book

First, we need to calculate the number of words in a page.

`1\ Page = Words * Lines`

`!\ Page = 12 * 38`

`1\ Page = 456`

Next, we calculate number of words in 500 pages

Multiply both sides by 500

`500 * 1\ Page = 456 * 500`

`500\ Pages = 228000`

Hence, there are 228000 words in the book
