Calculating Water Volume for Filling Containers: A Practical Guide

Introduction

Understanding the volume calculations of different containers is crucial in various practical applications, from daily household activities to complex manufacturing processes. In this article, we'll delve into a specific scenario where a cylindrical bucket is used to fill a cubic container with water. Understanding how to determine the number of times the bucket needs to be filled to fully fill the container will be explored through detailed calculations and explanations.

Calculating the Volume of the Cylindrical Bucket

The volume of a cylinder is a fundamental calculation for many applications. The formula for the volume of a cylinder is given by:

V πr2h

where

π (pi) is approximately 3.14159, r is the radius of the base of the cylinder, h is the height of the cylinder.

For our cylindrical bucket, the radius r is 8 cm and the height h is 18 cm.

Let's calculate the volume:

V_{bucket} π × 8^2 × 18 π × 64 × 18 1152π cm3

Calculating the Volume of the Cubic Container

When dealing with a cubic container, the volume is calculated differently. The formula for the volume of a cube is:

V a3

where

a is the length of an edge of the cube.

For the cubic container, the edge length a is 20 cm.

Let's calculate the volume:

V_{container} 20^3 8000 cm3

Determining the Number of Buckets Needed

To determine the number of times the cylindrical bucket needs to be used to fill the cubic container, we need to divide the volume of the container by the volume of the bucket:

Number of buckets V_{container} / V_{bucket}

Substituting the values we have calculated:

Number of buckets 8000 / (1152π)

Approximating π as 3.14159, we get:

V_{bucket} ≈ 3.14159 × 1152 ≈ 3618.5 ≈ 3619 cm3

Now, let's calculate the number of buckets:

Number of buckets ≈ 8000 / 3618.5 ≈ 2.209 ≈ 3 (rounded up)

Since we cannot use a fraction of a bucket, we round up to the nearest whole number, which is 3.

Conclusion

In summary, the cylindrical bucket needs to be used 3 times to fill the cubic container with water. This calculation demonstrates the practical application of volume calculations in real-world scenarios and emphasizes the importance of accurate volume measurements when filling containers with water or any other liquid.
