## How to Find Surface Area of a Cuboid?

A cuboid is defined as a three-dimensional analogue of a rectangle in two dimensions. The surface** **area of a cuboid is defined as the number of unit squares that can be fit into it and it is measured in square units. The surface area of a cuboid is calculated by the formula:

**The surface area of cuboid = 2(lb + bh + lh)**, where 'l' is the base length of the cuboid, 'b' is the base width of the cuboid, and 'h' is the height of the cuboid.

**Solved Examples on Surface Area of a Cuboid Calculator**

**Example 1:**

Find the surface area of a cuboid whose base length is 7 units, base width is 6 units, and height is 8 units?

**Solution:**

Given: l = 7 units, b = 6 units, and h = 8 units

The surface area of cuboid = 2(lb + bh + lh)

= 2((7 × 6) + (6 × 8) + (7 × 8))

= 2( 42 + 48 + 56)

= 2 × 146

= 292 square units.

Therefore, the surface area of a cuboid is 292 square units.

**Example 2:**

Find the surface area of a cuboid whose base length is 4 units, base width is 5 units, and height is 9 units?

**Solution:**

Given: l = 4 units, b = 5 units, and h = 9 units

The surface area of cuboid = 2(lb + bh + lh)

= 2((4 × 5) + (5 × 9) + (4 × 9))

= 2(20 + 45 + 36)

= 2 × 101

= 202 square units.

Therefore, the surface area of a cuboid is 292 square units.

Similarly, you can try the **Surface Area of a Cuboid Calculator** to find the surface area of a cuboid for

1) Base length = 8 units, base width = 6 units, and height = 10 units

2) Base length = 9 units, base width = 5 units, and height = 12 units
