# What is the formula of curved surface area of cube?

In the case of a cube, the lateral surface area consists of the area of four of the cube’s sides added together, or 4 times the area of one of the cube’s sides. Thus, the lateral surface area of a cube can be found using the formula 4s^2, where s is the side length of the cube.

The Curved surface area of a cube = 6a^2. Where, ‘a’ is the length of the side of each edge of the cube. since all sides of a cube are equal, ‘a’ is just the length of one side of a cube.

Also, what is the formula to find surface area? To find surface area for a rectangular prism, use the formula SA = 2ab + 2bc + 2ac, where a is the width, b is the height, and c is the length. If you’re trying to find the surface area of a triangular prism, use the formula SA = 2a + ph, where a is the area of the triangle, p is the perimeter, and h is the height.

Just so, what is the formula of curved surface area of cone?

The surface area of a cone is equal to the curved surface area plus the area of the base: π r 2 + π L r , pi r^2 + pi L r, πr2+πLr, where r denotes the radius of the base of the cone, and L denotes the slant height of the cone.

What is the total surface area of a cube?

In words, the surface area of a cube is the area of the six squares that cover it. The area of one of them is a*a, or a 2 . Since these are all the same, you can multiply one of them by six, so the surface area of a cube is 6 times one of the sides squared.

### What is the total surface area of a sphere?

Therefore, the Surface Area of a Sphere with radius r equals 4πr2 .

### What is difference between curved surface area and total surface area?

Curved surface area or lateral surface area is the area of the curved surface on these. Total surface area is the sum of curved surface area and the flat surfaces like base of a cylinder, base of a cone or base circular disc of a hemisphere.

### What is the total surface area of cone?

Find the lateral surface area of a right cone if the radius is 4 cm and the slant height is 5 cm. The formula for the total surface area of a right cone is T. S. A=πrl+πr2 .

### What is the diagonal of a cube?

The diagonal of a cube is nearly as simple as the Pythagorean theorem. It is very simple: (length)2 + (width)2 + (height)2 = (diagonal)2. In other words, you simply take the square root of the sum of the squares of the length, width, and height of the cube.

### What is total surface area in math?

Total Surface Area Defined Surface area means all the area that you can see in two dimensions – this means the length and width. For a two-dimensional object, that’s also its total surface area. In three dimensions, like a cube, a sphere, or a pyramid, the surfaces can’t all be seen at one time.

### What is CSA frustum?

Frustum of a cone: Cut a right circular cone with a plane parallel to the base of the cone, then the solid shape between the plane and the base of the cone is called the frustum of a cone. CSA of the frustum of a cone = πl( r1 + r2).

### What is the total surface area of a right circular cone?

Total surface area of a right circular cone = π(r + l) r. Volume of a right circular cone = 1/3π r2 h.

### What is slant height?

Slant Height. The slant height of an object (such as a frustum, or pyramid) is the distance measured along a lateral face from the base to the apex along the “center” of the face. In other words, it is the altitude of the triangle comprising a lateral face (Kern and Bland 1948, p. 50).

### What is the formula of CSA of cylinder?

The area of a rectangle is height (H) * width (W). The “width” in this case will be equivalent to the circumference of the cylinder’s base, which is 2 * π * radius (R). If you want to know the entire surface area of the cylinder, you need to add the area of the base and the top.

### What do you mean by curved surface area?

The curved surface area is the area of all the curved regions of your solid. If the object has both curved surface and flat surface then the curved surface area will be area of only the curved surface but the lateral surface area will include the curved area and the flat area excluding the base/bases.

### What is the circumference of a sphere called?

The Circumference of a circle or a sphere is equal to 6.2832 times the Radius. Circumference = 6.2832 ⋅ R. C = 2 ⋅ π ⋅ R. Figure 3., Circumference is 2 × π × Radius. The Circumference of a circle or a sphere is equal to 3.1416 times the Diameter.

### What is the meaning of lateral surface area?

The lateral surface of an object is the area of all the sides of the object, excluding the area of its base and top. For a cube, the lateral surface area would be the area of four sides. For a right circular cylinder of radius r and height h, the lateral area is the area of the side surface of the cylinder: A = 2πrh.
