Toys were packed in boxes of 115 each, 13 boxes = 115 × 13 = 1,495. Similarly, 65 × 22 = 1,430. This means the number of toys lies between 1,430 and 1,495 Since we pack n toys perfectly in n boxes, the number must be a square number. The only square number between 1,430 and 1,495 is 1,444. Hence, there are 1,444 toys.
