It’s C i’m pretty sure 16
You should ignore the negative answers because you can't have negative distance. For example, if you are going back 7 feet, you are still going 7 feet. In that situation, the answer would 7 not -7.
The volume inside is 27 cu. ft.
The surface area of a cube is the area of each face of the cube added together. There are 6 faces on a cube; 54/6 = 9 sq. ft. for each face of the cube.
Each face of a cube is a square, whose area is given by A=s²:
9 = s²
Take the square root of both sides:
√9 = √s²
3 = s
Each side of the square, or edge of the cube, is 3 ft.
This makes the volume 3(3)(3) = 27 cu. ft.

Step-by-step explanation:
It would be helpful to know the numbers of rows and columns, so we don't have to guess.
Any number of on-line calculators and/or graphing calculators can multiply these matrices for you. Excel and other spreadsheets can do this, too. Forming the 6 sums of 2 products is tedious to do by hand.
For example, the term in the product matrix at row 1 column 2 is the sum of products of the numbers in row 1 of the first matrix and column 2 of the second matrix:
4·1 + 0·1 = 4
