because you do
to find the surface area of the triangle we just need to multiply the length with breath. area=lengthXbreadth
Surface Area of a Cube = 6 a 2(a is the length of the side of each edge of the cube)In words, the surface area of a cube is the area of the six squares that cover it. The area of one of them is a*a, or a 2 . Since these are all the same, you can multiply one of them by six, so the surface area of a cube is 6 times one of the sides squared.
Rectangle Surface Area: L X W X 6 (the number of sides)
To find the surface area of a cube you find the area of one side then you multiply that by six because each side is exactly the same size.
well to find the area of an object, you multiply the length and height. si measure each of it's sides, and multiply together. that's how you find the polygon's area.
To calculate the surface area of a brick, you would find the surface area for each of the 6 sides, then add them together. To find the surface area of one of the faces/sides, you would multiply the length of the face in question by the width of that same face. If this is a regular brick, then the sides should match up, meaning if you do one side, then the opposite side should be the same surface area. To find the volume, you multiply the height of the brick by the length of the brick by the width of the brick.
you need measurements to figure out surface area. the simplest way to figure out the whole area of a dodecahedron is to find the surface area of one pentagon, then multiply by 12 (the number of sides of a dodecahedron)
Well [ph] is the first step which is perimeter times height. What you do is you multiply the height by the base. With that answer you multiply the number of sides of the shape which is 5 sides and the heighth. That is how you findd you answer :)
Multiply the sides

To find the area, multiply the height by the width.
To find the surface area of a square (or rectangle) you multiply the length times the width. Then to get the total area of a cube you add up the surface areas of all the square sides it has. I hope you can figure it out from there.
Find the area of one of the sides and then multiply it by 3 (3 sides to a triangular pyramid)Then work out the area of the base of the pyramid, and add it to the total area of all the sides.Area of a triangle = Base x Height / 2
Multiply 2 sides.
The only way to find the area is to have two sides to multiply them together unless you have the hypotenuse.
find area of all sides then add them
No, you must add, not multiply.
