In order to find the SA(surface area) of a three dimensional figure is simply the sum of the areas of all the surfaces of a figure. Formulas: Polyhedron=(FBa)2+(TB0)2+(LRi)2 Cylinder=2pi(RaRa)+2pi(RaH) Sphere=4pi(RR) F=front Ba=back T=top Bo=bottom L=left Ri=right Ra=radius H=height pi=3.14 nn=that number squared
least volume and most surface area is 3D triangle
There no such thing as perimeter of 3D objects . Generally perimeter is for 2D objects but you can find the surface are of a cube if you wished to ask that. Surface area of cube is - 6 x side x side.
The cone IS a 3d figure.
For a cuboid (a 3D rectangle) of width W, height H and depth D, the surface area is: (WH + WD + HD) x 2.
There's no such thing as "area of a box" unless you mean "surface area of a box." Length * width * height gives you the volume of a 3D box. Length * width gives area of a 2D rectangle. Surface area of a box can be found by calculating the area of each face and adding them together.
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

It is the total surface area of the shape.
You find the surface area of each of its six faces and add them together.
length times width i think* * * * *There are different formulae for calculating the surface areas of different 3D figures. If the 3D figure is a polyhedron, then each face is a ploygon and you can use the various formulae to calculate the area of each face and then add them together.There are straightforward equations for ellipsoids, and members of the conic family but other 3D shapes have more complicated formulae.
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.
