How do you find surface area of a cuboid?
The surface area of a cuboid can be calculated by adding together the areas of the six faces. The opposite faces of a cuboid are the same sized rectangles, so find the total area of the three different faces, then double to find the total surface area.
What is the formula of surface area of cuboid and cube?
Cube and Cuboid Formulas
| Cube | Cuboid |
|---|---|
| Total Surface Area = 6(side)2 | Total Surface area = 2 (Length x Breadth + breadth x height + Length x height) |
| Lateral Surface Area = 4 (Side)2 | Lateral Surface area = 2 height(length + breadth) |
| Volume of cube = (Side)3 | Volume of the cuboid = (length × breadth × height) |
How do you find the surface area and volume?
Surface Area Formulas:
- Volume = (1/3)πr2h.
- Lateral Surface Area = πrs = πr√(r2 + h2)
- Base Surface Area = πr2
- Total Surface Area. = L + B = πrs + πr2 = πr(s + r) = πr(r + √(r2 + h2))
Is LSA and CSA same?
Basically, the surface area can be classified as: Curved Surface Area (CSA) – It includes the area of all the curved surfaces. Lateral Surface Area (LSA) – It includes the area of all the surface excluding the top and bottom areas.
What is the lateral surface area of cuboid?
The lateral surface area of a cuboid is the combined surface area of the four vertical faces. The lateral surface area of cuboid will be, L= S = 2 (lb + bh + lh) – (2 × l × b) = (2 × l × h) + (2 × b × h) = 2h(l + b).
What is the formula to calculate the surface area of a cube?
The surface area of a cube is the total sum of the area of the six sides that cover it, and it is calculated by using the formula A = 6a^2. Measure the area of one side of the cube.
How many surfaces does a cuboid have?
In a cuboid there are 6 rectangular plane surfaces. There are 8 vertices and 12 edges. A cube is also a cuboid having all its 6 faces equal and square. Thus, a cube has all the six faces identical, whereas a cuboid has the opposite faces identical.
How can you find the volume of a cuboid?
The steps to calculate the volume of a cuboid are: Check if the given dimensions of cuboids are in the same units or not. If not, convert the dimensions into the same units. Once the dimensions are in the same units, multiply the length, breadth, and height of the cuboid. Write the unit in the end, once the value is obtained.
What is the equation for total surface area?
The body of the cone forms a sector of a circle when unwrapped. This sector’s area is given by the formula A = πrs, where s is the slant height of the cone (length from the cone’s point to base along the side). The equation for the surface area is therefore Surface Area = πr^2 + πrs.
