Her geography textbook has 160 + 70 = <<160+70=230>>230 pages

The sum of pages of her history and geography textbook is 160 + 230 = <<160+230=390>>390 pages

Her math textbook has 390/2 = <<390/2=195>>195 pages

Her science textbook has 160 x 2 = <<160*2=320>>320 pages

In total, there would be 160 + 230 + 195 + 320 = <<160+230+195+320=905>>905 pages

Suzanna's history textbook has 160 pages and her geography textbook has 70 more pages. Her math textbook has half of the sum of the first two books' pages, and her science textbook has twice the number of pages of her history textbook. If Suzanna stacks all her textbooks on her desk, how many pages would there be in total?
