The surface area of a cube is the total sum of the area of the six sides that cover it, and it is calculated by using the formula A = 6a^2. Measure the area of one side of the cube. Multiply that number by 6 to arrive at the total surface area of the cube.Continue Reading
The formula to calculate the surface area of a cube is A = 6a^2, where a equals one edge of the cube.
Calculate the area of one side of the cube by calculating the square of the length of one side of the cube.
Multiply the area of the side of the cube by 6 to get the total surface area of the cube.
The surface area of a trapezoid is calculated using the equation 1/2(a+b)*h, where "a" and "b" are the parallel sides of the trapezoid, and "h" is the vertical height. For example, if side "a" equals three, side "b" equals five and height "h" equals four, then the area equals 1/2(3+5)*4, or 16.Full Answer >
The perimeter of an object is the measurement of the sides of the object. Measuring the perimeter of a square or rectangle is easy, but measuring the perimeter of a cube is slightly more difficult. With a simple measurement, you can quickly calculate the perimeter of a cube.Full Answer >
To find the surface area of a sphere, use the formula 4(pi)r2. In this formula, r is equivalent to the radius. Pi represents the infinite number 3.141592..., which is usually rounded to 3.14.Full Answer >
The perimeter of a parallelogram, as for any polygon, is the sum of the lengths of its sides. The opposite sides of a parallelogram are parallel and have the same measurement. The formula for its perimeter is twice the sum of the base and the height or "2(b + h)."Full Answer >
