If an octagon has a height of 17' and a base of 13'6" then it is not a regular octagon. In that case, a lot more information is required before its area can be calculated.
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
Base * height is surface area or (bh)
A cone with height 24 and the base diameter 7 has a surface area of 305.17 units2
area of base x height
Area = base*height
The surface area is a function of the height (or slant height) and the radius of the base. So, the slant height is a function of the surface area and the base-radius. Since the latter is unknown, the slant height cannot be calculated.
False...
The formula to find the surface area of a parallelogram is Base*Height.
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.
The surface area of a prism is the two bases and all the sides A = 2 *area of base + Perimeter of base * Height of prism.
volume is length x base x height and surface area is volume divided by height~
if you mean surface area, the area of the base multiplied by the height
