### What is meant by the Surface Area of a Box?

In Mathematics, Rectangular Prism or Box is a three-dimensional figure in which six faces of the solid are rectangles. It is also called cuboid. Opposite faces of the box are equal in measure and have 12 sides and 8 vertices normally. The Surface Area of a Box is equal to the sum of the areas of each side of the box. If “l” is the length, “w” is the width and “h” is the height surface area of the box is given by the formula

Surface Area of the box = **2 (lw+lh+hw) square units**

### How to Calculate Surface Area of a Box

In order to calculate the surface area of a box or rectangular prism all you need to do is find the areas of each side and sum up all those.

i.e. A = 2*(A1+A2+A3)

if “l” is the length “h” is the height and “w” is the width then Areas of all the three sides would be as follows

A1 = l * w

A2 = w * h

A3 = l * h

Thus, the final formula would be A = 2 *(l * w+w * h+l * h)

A = 2(lw+wh+lh)

∴ Surface area of a Box A = 2(lw+wh+lh) |

If you aren’t Clear about the Surface Area of a Box concept check out the solved examples along with step by step explanation. You will be familiar with how to solve the problems on the Surface Area of a Box by referring to the below examples.

**Example**

Calculate the Surface Area of a Box for the length, width, height given as 3Cm, 4 Cm, 5 Cm respectively?

**Solution: **Given Length of a Box = 3 Cm

Width of a Box = 4 Cm

Height of a Box = 5 Cm

Formula to find the Surface Area of a Box is given by

**A = 2(lw+wh+lh)**

Substitute the given values in the formula and then we will get the result as under

A = 2(3*4+4*5+3*5)

=2(12+20+15)

=2(47)

= 94 Cm^{2}

∴ The surface area of a Box for length 3 cm, width 4 cm, and height 5 cm is **94.0 cm ^{2}**
