In this article, we will understand how to compute the surface area and volume the cuboid. Cuboid is a three-dimensional object with six faces of rectangle shape which means it has sides of different length and breadth. The difference between a cube and cuboid is that a cube has equal length, height and breadth whereas in cuboids these three are not sameThe surface area of cuboid is calculated using the formula −2*( length *width + width* height + height*length)The area of the cuboid is calculated using the formula −length*width*heightBelow is a demonstration of the same −InputSuppose our input is −Length= ...

In this article, we will understand how to find the area of a trapezium. Trapezium is a type of quadrilateral that has at least one pair of side parallel to each other. The parallel sides of a trapezium are called bases and the non-parallel sides of a trapezium are called legs. It is also called a trapezoid.The area of a trapezium is calculated using the formula −(height/2 * (side_1 + side_2). i.e. Area = ½ x (sum of the lengths of the parallel sides) x perpendicular distance between parallel sidesBelow is a demonstration of the same. Area of a trapezium ... Read More
