216 sqft squared feet

Step-by-step explanation:

6x6=36       36x6=216 your essentially finding the square and then adding a third dimension by multiplying it by its z value 2 dimensional objects have 2 dimension x and y. side to side(x) and up and down(y) when you add a 3rd dimension it adds another measurement which was 6 so you multiply the 2 dimensional object by the 3rd dimension and get the cube instead of square

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer
