Introduction

In geometry, a cuboid is a three-dimensional solid object with six rectangular faces. The area of the four walls of a cuboid can be calculated using the formula: Area = 2(lb + bh + hl), where l is the length, b is the breadth, and h is the height of the cuboid. In this article, we will find the area of four walls of the cuboids with the following dimensions:

(i) l = 2 m, b = 1.5 m, h = 3 m
(ii) l = 15 m, b = 10 m, h = 8 m
(iii) l = 2.5 m, b = 2 m, h = 4 m

Calculating the Area of Four Walls of the Cuboid (i)

To find the area of four walls of the cuboid (i), we will use the formula: Area = 2(lb + bh + hl). Substituting the values of l, b, and h, we get:

Area = 2(2 × 1.5 + 1.5 × 3 + 3 × 2) = 2(3 + 4.5 + 6) = 2 × 13.5 = 27 m²

Calculating the Area of Four Walls of the Cuboid (ii)

To find the area of four walls of the cuboid (ii), we will use the formula: Area = 2(lb + bh + hl). Substituting the values of l, b, and h, we get:

Area = 2(15 × 10 + 10 × 8 + 8 × 15) = 2(150 + 80 + 120) = 2 × 350 = 700 m²

Calculating the Area of Four Walls of the Cuboid (iii)

To find the area of four walls of the cuboid (iii), we will use the formula: Area = 2(lb + bh + hl). Substituting the values of l, b, and h, we get:

Area = 2(2.5 × 2 + 2 × 4 + 4 × 2.5) = 2(5 + 8 + 10) = 2 × 23 = 46 m²

Conclusion

In this article, we have calculated the area of four walls of the cuboids with the following dimensions:

(i) l = 2 m, b = 1.5 m, h = 3 m
(ii) l = 15 m, b = 10 m, h = 8 m
(iii) l = 2.5 m, b = 2 m, h = 4 m

The area of four walls of the cuboid (i) is 27 m², the area of four walls of the cuboid (ii) is 700 m², and the area of four walls of the cuboid (iii) is 46 m².
