Six The base is a square. It's measurement is s = 4 Base = 4^2 Base = 16 ft^2
One triangle A = 1/2 * b * h A = 1/2 * 4 * 7 A = 14 tt^2
Four triangles A = 4 * 14 A = 56 ft^2
Total Area = 56 + 16 = 72 ft^2 Answer 72 square feet
Seven Triangles Area of 1 triangle = 1/2 * 10 * 13 Area of 1 triangle = 65
Area of 6 triangles Area of 6 triangles = 6 * area of 1 triangle Area of 6 triangles = 390
Base As near as I can tell, the base is a hexagon. It's using a rather out of the way method of drawing it. I will assume it is a regular hexagon. The area of a regular hexagon is 3 sqrt(3)/2 * S^2 where s is the side of the hexagon.
Area = 3sqrt(3)/2 s^2 s = 10 Area = 3sqrt(3)/2 10^2 Area = 5.1962 * 100 /2 Area = 259.81
Total area Total area = area of the base + area of the triangles Total area = 259.81 + 390 Total area (rounded ) = 650

I'll do one more in this batch and then you'll need to repost again.

If you draw two diagonals on the base of the figure, the intersection point will meet the base of the height. Read that a couple of times. Join the intersection to the midpoint of the length of the square bottom. You should get 3.5
x is found by using the pythagorean theorem. h = 6 s = 3.5 x = ????
x^2 = 6^2 + 3.5^2 x^2 = 36 + 12.25 x^2 = 48.25 x = sqrt(48.25) x = 6.95
Because vol= length x width x height , and assuming that the height is 11.5 because breadth means width but you already have a width then, vol= 11.5 x 7.4 x 11.5, vol = 978.65
