The volume of the bed of the truck is 2.5 x 1.5 x 1.0 = 3.75 cubic meters.
total trips = 7 / 3.75 = 1.87, round up to 2.
They will need to make 2 trips.
The numbers 1 to 72 add up to (1+72) x 72/2 = 73 x 36 = 2628
If we take away what Josh got we have 2628 - 2521 = 107
Pages in a book are odd on the first side and even on the second, so pages 11 and 12 are on the same sheet.
107 / 2 = 53.5 so the missing page had 53 on one side and 54 on the other side.
The remaining pages would have been numbered 1, 2, 3, ..., 51, 52, 55, 56, ... 71, 72
Step-by-step explanation:
.
Total pages=125
Pages read in 1 day=12
Pages read in 4 days=4×12=48
Left pages to read=125-48=77 pages
