The surface area of a rectangular pyramid is found by adding the area of the base to the combined area of the four triangular sides. The area of the base is found by multiplying length times width. The area of each trian... More »

A hexagonal pyramid's surface area is given by 3ab + 3bs; where "s" is the slant height, "b" is the base length and "a" is the pyramid's apothem length. A hexagonal pyramid is sometimes referred to as a heptahedron; it h... More »

A triangular-based pyramid is a convex solid figure with a base in the shape of a triangle and triangular sides that meet at points called vertices, according to New South Wales Board of Studies. Convex means that all it... More » Math Geometry

The formula for calculating the total surface area of a pyramid is: S = (1/2)Pl + B. The surface area of a pyramid is the total sum of the lateral area combined with the area of the base. More »

The surface area of a rectangular prism is the combined surface areas of all six of its sides. Because opposing sides are always the same size, the total surface can be determined by using the length, width and height of... More »

The surface area of a right square pyramid is determined by adding the square of the length of the base to four times the quotient of the base length times the height divided by two. The formula is written as SA=b^2 + 4(... More » Math Geometry Shapes

A right circular cone's surface area is made up of two parts: the top part with the slanted sides and the circular base. The total surface area is found by finding the surface area of each part and adding them together. More » Math Geometry Shapes
