Answer:
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
