Surface area is all the areas for a 3 figure. Area is for only on side of a 3d figure
It is the total surface area.
K, well there is no surface area of a triangle, because a triangle is a 2s figure. Surface area is for a 3d figure. To find the regular area of a triangle the formula is 1/2 of the base X the height :) gl :P
You find the surface area of each of its six faces and add them together.
Yes, if it is bound by plane figures, just add the area of each plane figure. If it has a curved surface, divide it into many small pieces, to approximate the area with small rectangles or triangles, then add them up.

The trapezoid is a plane figure which has surface Area, but no volume but if there was a 3d figure your equation would be. The Surface Area of a trapezoid = ½(b1+b2) x h X Height of figure.
It depends on the type of figure. If it is a 2D figure, then it is called area. If it is a 3D figure, then it is called volume.
Sum the areas of all four faces.
It depends, but in let's look at a simple example to help you see how. How would you find the surface area of a cube. Find the surface area of one of the faces and since there are six of those, multiply it by 6. For example, a 2x2x2 cube. Each face has a surface area of 4 and there are 6 of them so the total surface area is 24 units. We do the same thing with other 3d objects, but it may be harder to find the surface area of faces. In face, sometimes there are no faces and we may need calculus to find the surface area.
A 2D interior will be length times width (a flat shape) as in the area of a floor.A 3D figure would be length times width times depth (a raised shape) as in a box.The units used would depend. A floor would be in feet and inches or metres and centimetres.A 3D figure would be in a similar measurement, but given in cubic units.
