Answer:
#1) 108.375 cubic inches
Step-by-step explanation:
For a pan of dimensions 8.5 in x 8.5 in, with height 2.25 in:
If cornbread fills to .75 in from the top, the height of cornbread is 2.25-.75 = 1.5 in
Volume = length*width*height (for rectangular prisms)
So Volume of corn bread = 1.5*8.5^2 = 108.375 cubic inches
For the second part, it is a poorly worded question. Squares are two dimensional, so it realistically cannot be cut into squares. If the question means cubes, the answer is yes to a certain extent. Since the height is exactly 1.5 in, and the pan is 8.5 in x 8.5 in, Marita can cut the cornbread into squares, but she cannot cut all of it into squares since 8.5/1.5 is not a whole number.
