Divide 405 by 6 which is 67.5
So 67.5 per hour but it wants minutes
So divide 67.5 by 60 (minutes in an hour) and you’ll get 1.125 pages per minute
The answer is 240 because 11 x 8 is 88 but you divide by 2 since it's a triangle so you get 44 and since there's 4 triangles you do 44 x 4 and get 176 then 8 x 8 is 64 plus 176 is 240
