Answer:
24x40
Everytime the dimensions double, so the forth time the dimensions would be:
24 wide, 40 long.
Answer:
24 in wide and 40 in long.
Step-by-step explanation:
Each dimension is doubled:
width 3 goes to 6, and 6 goes to 12.
length 5 goes to 10, and 10 goes to 20.
So 4th cake will have dimension 2*12 and 2*20 in.
