How to find the surface area of a cuboid?

The surface area of a cuboid is the sum of the areas of each of the six faces. If we call the length of each of the sides a, b, c, d, e, and f, then the surface area is a2 + b2 + c2 + d2 + e2 + f2. If you have the four sides handy, you can find the surface area by multiplying each length by the cosine of the angle formed by the adjacent faces and adding the results

How to find the surface area of a cube?

The surface area of a cube is equal to the sum of the areas of all the faces of the cube. To find the surface area of a cube, first, you need to find the area of each face. The area of each face is equal to the base multiplied by the height, because each face is a rectangle. So, find the perimeter of the cube and then use the multiplication equation to find the surface area of the cube.

How to find the surface area of a rectangular prism?

The surface area of a rectangular prism is equal to the sum of the areas of its six faces. If the base of a rectangular prism is a square, the surface area of the prism can be found by multiplying the length of each of the four sides by their height. If you have a rectangular prism whose four sides have the same length but different widths, you need to find the surface area by multiplying the length of each side by the product of the two other dimensions.

How to find the surface area of a triangular prism?

To find the surface area of a regular triangular prism, all you need to do is multiply the base area by the height and add the three internal (or “shadow”) triangles. This is because the surface area of a prism is equal to the sum of the areas of the three internal triangles.

How to find the surface area of a rhomboid?

A rhomboid is a quadrilateral with four sides that form 90-degree angles. The area of a rhomboid equals the length of its base multiplied by its height or width. Use the Pythagorean Theorem to find the length of each side of a rhomboid. Add the lengths of the four sides together to find the surface area.
