The bulk of the question is irrelevant ! If all you need is the surface area of the 3-inch cube, simply multiply 3 x 3 x 6 to give 54 square inches !
total surface area is all of the area. ex. for a square pyramid it would be the area of the square on the bottom and the four triangle sides lateral surface area is all the surface area EXCEPT the base. ex. for a square pyramid it would be the area of the four sides of the pyramid. the bottom square is NOT included. for a triangular prism it would be the area of the three rectangle sides, NOT the two triangular sides
The surface area depends on the shape, not just the length of sides.
You need to find the surface area of each of the six sides. There are three pairs of identical sides. So here is how to do it Surface Area = [2x (25x19)] + [2x(19x5.5)] + [2x(25x5.5)] = 950 + 209 + 275 = 1434 square units
A triangular prism is a three-sided prism with three faces joining corresponding sides. The formula for its surface area is SA = wh + lw + lh + ls, where l=length, h=height, w=width and s=side.

Total surface are is the sum of the areas of all the sides of a three-dimensional object.
Surface area is the area of all the sides of a 3D object, but area could be anything. e.g. Area is the surface of a 2D object or if you say the area of all the sides, it means the same as Surface area. -----=-----=-----=-----=-----=-----=-----=-----=-----=-----=-----=-----=-----=-----= By Austin from Covenant Christian School
Surface area if a cube with six sides can be calculated by finding the surface area of one side and then multiplying the result by 6.
The surface area is 88.
Surface area is 294cm2 Volume is 343cm3
Surface Area of a cube is equal to the sum of the area of it sides. Each of its sides are square of side length a. Each side has area of a2. There are 6 sides on a cube. a2 + a2+ a2+ a2+ a2+ a2 = 6a2 Therefore: Surface area of a cube is 6a2
An area of land bordered on three sides by water is a peninsula.
Ratio of sides = 10/5 = 2 So ratio of surface area = 22= 4Ratio of sides = 10/5 = 2 So ratio of surface area = 22= 4Ratio of sides = 10/5 = 2 So ratio of surface area = 22= 4Ratio of sides = 10/5 = 2 So ratio of surface area = 22= 4
If the length of the sides triples, the surface area increases 9-fold.
The surface area depends on the shape, not just the length of sides.
