Assuming the base is square, then:
The area of the two bases = 2 x 8 x 8 = 128 cm
The area of the four side areas = 4 x 8 x 12 = 384 cm
Total area = 128 + 384 = 512 cm
The surface area of a cube is directly related to the length of its sides. Specifically, the surface area ( A ) can be calculated using the formula ( A = 6s^2 ), where ( s ) is the length of a side. This means that if the side length increases, the surface area increases with the square of that length, demonstrating a quadratic relationship. Conversely, if the side length decreases, the surface area decreases in a similar manner.
To find the surface area of a hexagonal pencil, we need to calculate both the lateral surface area and the area of the hexagonal bases. The lateral surface area is given by the formula ( A_{lateral} = perimeter \times height ). The perimeter of a hexagon with a side length ( s ) is ( 6s ), and the area of the hexagonal base is ( \frac{3\sqrt{3}}{2}s^2 ). Assuming the hexagonal pencil has a side length of 4 mm, the total surface area would be the sum of the lateral surface area and twice the area of the base. However, to provide an exact numerical answer, we need the side length of the hexagon, which hasn't been specified. If we assume the side length is 4 mm, the calculations would proceed from there.
To calculate the surface area of a regular pyramid, we need the area of the base and the area of the triangular faces. Assuming the base is a square with a side length of 9, the area of the base is (9^2 = 81). The slant height can be calculated using the height of 9 and half the base length (4.5) using the Pythagorean theorem. Finally, the total surface area is the base area plus the area of the four triangular faces.
Such a pyramid cannot exist. If it is a regular pyramid with side length 8, its slant height MUST be less than 8. In fact, it is approx 6.39.
Do length X height for one side. Then multiply that by 6 because there are 6 sides, and it is a cube, so each side is equal.

6 centimetres( to find surface area one must multiply height by height, width by width and length by length. Then you must add the products together and you get the surface area. To get the side lengths from a surface area you must reverse and divide it by 3[height,length and width]. In your case that would be 18. Then you must find a number that when multiplied by 3 equals the quotient of the first division{18} and there you have it 6). This only works on cubes.

Total surface area= 1/2 times the perimeter of the base times the slant height plus the area of the base Lateral surface area= 1/2 times the perimeter times the slant height
The surface area can not be found from this information.
Base * height is surface area or (bh)
PerimeterThe perimeter of a polygon is the sum of the lengths of all its sides.What is the perimeter of a square having side-length 74 cm? Since a square has 4 sides of equal length, the perimeter of the square is 74 + 74 + 74 + 74 = 4 × 74 = 296.
