Only one. All squares are figures drawn entirely on a flat surface.
A trapezoid has one surface and its surface area in square units is 0.5*(sum of parallel sides)*height
Cube has 6 surfaces Each surface is 812 x 812 = 659344 square inches All 6 surfaces will total 659344 x 6 = 3956064 square inches
A cuboid has 6 sides/faces/flat surfaces.
2 flat surfaces unless it is rolled up in which case it has 2 curved surfaces.
A square has 4 flat surfaces.

A cube has 6 square surfaces, 12 edges and 8 vertices
A square base, and four triangular shaped sides equals five flat surfaces.
Six. Six. Six. Six.
Yes, it has five surfaces.
It depends . . . check the back of the paint can -- it should tell. If not, figure 350 to 400 square feet per gallon on smoothish surfaces and perhaps 200 square feet on roughish surfaces.
A square based pyramid has 5 faces, 8 edges and 5 vertices
