If the octagon at the base is regular, the side of the octagon is s and the height of the prism is h, the area of each octagonal base (Ab) is
Ab = 2(√2 +1) s2
The perimeter of the octagon is
P = 8s
Then the surface area of the prism is
As = 2 Ab + Ph
The volume of the prism is
V = Ab h
The Area of its base times the height of the shape.
The Surface area of a triangle = 0.5*base*height The volume of a prism = area of its cross-section*length
The surface are of a right prism is equal to twice the area of its base plus the perimeter of the base multiplied with the height of the prism. The volume can be determined by multiplying the Area of the base by the height of the prism.
No.
That depends on how many faces this particular prism has.
Because it's a 3 dimensional shape that has surface area and volume.
It is the area of the base X the height.
The Area of its base times the height of the shape.
The Surface area of a triangle = 0.5*base*height The volume of a prism = area of its cross-section*length
An octagonal prism is a three-dimensional geometric shape with two parallel octagonal bases connected by rectangular lateral faces. It has a total of 10 faces (2 octagons and 8 rectangles), 24 edges, and 16 vertices. The height of the prism is the distance between the two octagonal bases, and its volume can be calculated using the formula ( V = \text{Base Area} \times \text{Height} ). The surface area is calculated by adding the areas of the two bases and the lateral faces.
The surface are of a right prism is equal to twice the area of its base plus the perimeter of the base multiplied with the height of the prism. The volume can be determined by multiplying the Area of the base by the height of the prism.
To find the volume of a rectangular prism when given the surface area, we need more information than just the surface area. The surface area of a rectangular prism is calculated using the formula 2lw + 2lh + 2wh, where l, w, and h are the length, width, and height of the prism, respectively. Without knowing at least one of these dimensions, we cannot determine the volume of the prism.
No, doubling the volume of a rectangular prism does not necessarily double the surface area. The relationship between volume and surface area depends on the dimensions of the prism. For example, if you double the height while keeping the base area constant, the volume increases, but the surface area may not double. The specific changes in dimensions will determine the new surface area.
Calculating the volume (V) of an octagonal prism involves finding the area (A) of the octagon that is an end (or base), and then simply multiplying it by the length (L) of the prism. The area of an octagon with a side of length s is given by this formula: Aoctagon = 2 (1 + sqrt 2) s2 or about 4.8284 s2 If we take that and multiply it by the length of the prism, we should arrive at the volume thus: Voctagonal prism = L x Aoctagon
Surface area is squared; volume is cubed.
Assuming you mean a rectangular prism, you get the smallest surface area if the prism is a cube. You can calculate the required length of side to get that volume; then, based on that, the corresponding surface area.
Volume = base area x height = 25 x 1.5 = 37.5 cubic metres.
