Oct 13, 2025 by recoveryshake.com 130 views

Introduction

In this article, we will explore a problem involving a rectangular container and the calculation of the volume of water poured into it. The container is initially one-third filled with water, and then some water is poured into it, making it half full. We will use mathematical concepts to determine the volume of water added to the container.

Understanding the Problem

The container is a rectangular prism with dimensions 12 cm long, 8 cm wide, and 20 cm high. When it is one-third filled with water, the volume of water in the container is given by:

Volume of water = (1/3) × Length × Width × Height = (1/3) × 12 × 8 × 20 = 640 cm³

Calculating the Volume of Water Added

When the container is half filled with water, the volume of water in the container is given by:

Volume of water = (1/2) × Length × Width × Height = (1/2) × 12 × 8 × 20 = 960 cm³

Since the container was initially one-third filled with water, the volume of water added to the container is the difference between the volume of water when the container is half full and the volume of water when it is one-third full:

Volume of water added = Volume of water when half full - Volume of water when one-third full = 960 cm³ - 640 cm³ = 320 cm³

Conclusion

In this article, we have calculated the volume of water poured into a rectangular container. The container was initially one-third filled with water, and then some water was poured into it, making it half full. We used mathematical concepts to determine the volume of water added to the container. The volume of water added to the container is 320 cm³.

Mathematical Formulas Used

Volume of a rectangular prism = Length × Width × Height
Volume of water when one-third full = (1/3) × Length × Width × Height
Volume of water when half full = (1/2) × Length × Width × Height

Step-by-Step Solution

Calculate the volume of water when the container is one-third full:
- Volume of water = (1/3) × Length × Width × Height
- Volume of water = (1/3) × 12 × 8 × 20
- Volume of water = 640 cm³
Calculate the volume of water when the container is half full:
- Volume of water = (1/2) × Length × Width × Height
- Volume of water = (1/2) × 12 × 8 × 20
- Volume of water = 960 cm³
Calculate the volume of water added to the container:
- Volume of water added = Volume of water when half full - Volume of water when one-third full
- Volume of water added = 960 cm³ - 640 cm³
- Volume of water added = 320 cm³
