Ok so if it’s 112 then it would be 224 because the length is double the width.

Answer: 450

Step-by-step explanation: Because 7 of the boxes are 112 there are 8 more which is 113 add 112 and 113 because that’s the length of all 15 blocks and you get 225 than you multiply by 2 because it’s twice the width and get 450
