Introduction

In geometry, a rectangular prism is a three-dimensional shape with length, breadth, and height. Given the dimensions of a rectangular prism, we can calculate its volume and surface area. In this article, we will explore the formulas and calculations involved in finding the volume and surface area of a rectangular prism.

Calculating Volume

The volume of a rectangular prism is calculated by multiplying its length, breadth, and height. The formula for the volume of a rectangular prism is:

V = l × b × h

where V is the volume, l is the length, b is the breadth, and h is the height.

Given Dimensions

The dimensions of the rectangular prism are:

  • Length (l): 4.5 cm
  • Breadth (b): 3.5 cm
  • Height (h): 4 cm

Calculating Volume

Substituting the given values into the formula, we get:

V = 4.5 × 3.5 × 4

V = 63

Therefore, the volume of the rectangular prism is 63 cubic centimeters.

Calculating Surface Area

The surface area of a rectangular prism is calculated by finding the area of each face and adding them together. The formula for the surface area of a rectangular prism is:

SA = 2lw + 2lh + 2wh

where SA is the surface area, l is the length, w is the width, and h is the height.

Given Dimensions

The dimensions of the rectangular prism are:

  • Length (l): 4.5 cm
  • Breadth (b): 3.5 cm
  • Height (h): 4 cm

Calculating Surface Area

Substituting the given values into the formula, we get:

SA = 2(4.5 × 3.5) + 2(4.5 × 4) + 2(3.5 × 4)

SA = 2(15.75) + 2(18) + 2(14)

SA = 31.5 + 36 + 28

SA = 95.5

Therefore, the surface area of the rectangular prism is 95.5 square centimeters.

Conclusion

In this article, we have calculated the volume and surface area of a rectangular prism given its dimensions. The volume of the prism is 63 cubic centimeters, and the surface area is 95.5 square centimeters. These calculations are essential in various fields such as engineering, architecture, and design.
