How do you find the surface area of a rectagle?
to find the surface area of the triangle we just need to multiply the length with breath. area=lengthXbreadth
How to find the surface area of a cube?
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.
How you find the surface area?
Rectangle Surface Area: L X W X 6 (the number of sides)
What is a sentence with surface area in it?
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.
What does find the area of each polygon mean?
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.
How do you calulate the surface area of the brick and its volume?
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.
What is the surface area of a dodecehedron?
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)
What is the formula to find the surface area of a pentagonal prism?
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 :)
How fo you find the area of a polygon?
Multiply the sides

Can you find the surface area on a sheet of paper?
To find the area, multiply the height by the width.
If cubes side is 1 cm how much is its total surface area?
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.
How do you find the total surface rea of a trianguar pyramid?
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
How do you find the area of a square with a side 7.5?
Multiply 2 sides.
How do you find the area of a quadrilateral if only of its four sides are known?
The only way to find the area is to have two sides to multiply them together unless you have the hypotenuse.
How do you determine the surface area of a solid?
find area of all sides then add them
Is it true that to find the surface area of a three dimensional figure you must find the area of each of it faces and multiply together?
No, you must add, not multiply.
