well as how to apply it. You will be able to answer issues involving the surface area of the cuboid once you have mastered this chapter for **surface area of cuboid**.

The total space filled by a cuboid is its surface area. A cuboid is a six-sided three-dimensional object with a rectangle on each face. We’ll study how to determine the formula for the cuboid’s surface area as **What is a cuboid?**

A cuboid is a solid or three-dimensional shape with six rectangular sides known as faces. A cuboid’s faces are all rectangles, and all of its corners are 90 degrees. It has 12 edges and 8 vertices. A cuboid’s opposing faces are always equal. It signifies that the cuboid’s opposite surfaces have the same dimension. Total Surface Area (TSA), Lateral or Curved Surface Area (CSA), and Volume are the cuboid’s measurements. The surface areas of the cube are measured in square units, but the volume is measured in cubic units.

**What is the Cuboid’s Surface Area?**

The entire area of the cuboid’s surfaces is its surface area. Because a cuboid is a three-dimensional solid form (whose dimensions are length, breadth, and height), the value of its surface area is determined by those dimensions. The value of a cuboid’s surface area varies when any of its dimensions are changed. The (unit)2 is the unit for the surface area of a cuboid. Surface area is measured in square metres or square centimetres in metric measurements, and square inches or square feet in USCS units.

**Cuboid Surface Area Formula**

There are two types of surface areas that a cuboid can have:

- Surface Area Total
- Area of Lateral Surface

**Cuboid Lateral Surface Area**

The combined surface area of a cuboid’s four vertical sides is the lateral surface area. The two horizontal faces (face 1 and face 2) will be deleted from the total surface area in the picture above, leaving just the vertical faces.

Assume there is a cuboidal room to better comprehend this. The overall surface area of the room will be the sum of the six faces (the four vertical walls + the floor + the ceiling), whereas the lateral surface area will be the sum of the four vertical walls (the areas of the floor and the ceiling are not added).

**How can you calculate the surface area of the cuboid?**

The area of each surface of a cuboid is the surface area of the cuboid. The surface of a cuboid may be estimated by determining the type of area required in a certain context. The following are the steps to calculating a cuboid’s surface area:

- Step 1: Determine if the cuboids’ dimensions are in the same units. If they aren’t in the same units, convert them.
- Step 2: Once the dimensions have been converted to the same units, understand why it is necessary to compute the total surface area or lateral surface area in a certain case.
- Step 3: Use the formula 2 (lb + bh + lh) or 2h(l +b) to get total surface area or lateral surface area.
- Step 4: Fill in the blanks with the unit’s name.

**Conclusion **

Enrol in the course by **Cuemath** and the well trained and experienced staff can help you in understanding the concept. A cuboid is a three-dimensional shape circumscribed by six rectangular planes with distinct length, width, and height magnitudes. It might be cuboid if you notice a box, brick, or anything in the shape of a rectangle around you. When viewed from any of the ends, a cuboid (3-dimensional) may be seen to be made up of rectangles (2-dimensional) of various dimensions. In this article, we’ll go over the definition of a cuboid, as well as the total and lateral surface area of a cuboid.
