The capacity of the cookie tin represents the volume of rectangular prism. Volume of a rectangular prism can be determined by the formula
V = l × w × h
From the question above, we know that
l = 14 in
w = 7.6 in
h = 3.4 in
Plug the numbers into the formula
V = l × w × h
V = 14 × 7.6 × 3.4
V = 361.76
The capacity is 361.76 cubic inches
