54 square feet. A cube has 6 identical surfaces. A 3 ft cube has 6 surfaces each measuring 3ft x 3ft = 9 sq.ft. per surface. So 9 x 6 = 54 sq. ft. total surface area.
Yes, using two 3ft x 3ft tiles.
To find the area of 3ft by 1ft, you multiply the two. So the area is 3 square feet.
yes.
Square yards would be a surface area measurement (3ft x 3ft), to measure surface area of a flat surface measure the length and width (in yards) then simply the two together .for example 5yards x 2 yards = 10 square yards=10 yards2To measure the surface area of a nonuniform surface you would need very specific tools and programs, that are not easily available.Measuring the square yards of sand is very unusual and what you may mean is "how do I measure cubic yards of sand?"

The answer depends on what the shape is: a 2-dimensional triangle, a 3-dimensional cuboid, an ellipsoid or something else.
Yes we can with the help of 2 tiles placed side-by-side.
2 x (11 x 3) + 2 x (11 x 3) + 2 x (3 x 3) = 150 square feet
