How do you find the surface area of a 3D triangle?
Sum the areas of all four faces.
How do you find the surface area of a 3d object?
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.
How is the surface area different from area?
Surface area is all the areas for a 3 figure. Area is for only on side of a 3d figure
What is a formula for surface area of triangle?
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
How does a 2D shape look different from a 3D shape?
A 2D shape is flat and only has a surface area whereas a 3D shape is an object that has surface area and volume.
