The width of the four rectangles will be the same as the height of the prism. The length of the four rectangles will be the sum of the four sides of the trapezoid, the two bases, and the other two sides. The surface area can be given with this formula: Surface Area of Trapezoidal Prism = (b1+b2)h + PH.

Let's say the triangular prism has a length of 8 inches, a width of 8 inches, a height of 3 inches and a side length of 5 inches. Using the formula for surface area of a triangular prism, SA = wh + lw + lh + ls, we calculate a surface area of 152 square inches. Step 3: Subtract the overlapping parts from each figure.

The volume of a rectangular prism is given in two equations: V = (area of base) * (height) and V = (length) * (width) * (height). The surface area of a rectangular prism is the sum of the area of its six faces: Surface Area = 2_l_w + 2_w_h + 2_l_h.

Area of a Trapezium. A trapezium, also known as a trapezoid, is a quadrilateral in which a pair of sides are parallel, but the other pair of opposite sides are non-parallel. The area of a trapezium is computed with the following formula: Area = 1 2 × Sum of parallel sides × Distance between them .

Learn how to find the volume and the surface area of a prism. ... The volume of a prism is given by the area of its base multiplied by its height (the distance between its bases). While the total surface area of a prism is given by the sum of the areas of all the plane shapes making up the prism.

If you have a hemispherical object then it has a base which is a circle of radius r. The area of a circle of radius r is π r2 and thus if the hemisphere is meant to include the base then the surface area is 2 π r2 + π r2 = 3 π r2. Hence in this case 3 π r2 = 1062. Solve for r.

Formula for Volume of a Trapezoidal Prism. If the prism length is L,trapezoid base width B, trapezoid top width A, and trapezoid height H, then the volume of the prism is given by the four-variable formula: V(L, B, A, H) = LH(A + B)/2. In other words, multiply together the length, height, and average of A and B.

A triangular prism has three rectangular sides and two triangular faces. To find the area of the rectangular sides, use the formula A = lw, where A = area, l = length, and h = height. To find the area of the triangular faces, use the formula A = 1/2bh, where A = area, b = base, and h = height.

For a square-based prism with a given volume, the minimum surface area occurs when the prism is a cube. Given a volume, you can find the dimensions of a square-based prism with minimum surface area by solving for s in the formula V = s3, where V is the given volume and s is the length of a side of the cube.

To find the surface area of a prism (or any other geometric solid) we open the solid like a carton box and flatten it out to find all included geometric forms. To find the volume of a prism (it doesn't matter if it is rectangular or triangular) we multiply the area of the base, called the base area B, by the height h.

Explanation: To find the area of a trapezoid, multiply the sum of the bases (the parallel sides) by the height (the perpendicular distance between the bases), and then divide by 2.
