Answer:
b. 1.129 inch
Explanation:
If the pan were completely filled, it would hold ...
(7 in)(11 in)(2 in) = 154 in^3
of batter, or ...
(154 in^3)(0.069 cups/in^3) = 10.626 cups
Since it is filled with only 6 cups, and the depth is proportional to the volume, the depth is ...
depth/(2 in) = (6 cups)/(10.626 cups)
Multiplying by 2 in, we get ...
depth = (2 in)(6/10.626) = 12/10.626 in
depth ≈ 1.129 in
