Calculating Cubic Inches in a Junction Box
To find out how many cubic inches are contained in a junction box that measures 12 × 12 × 4 inches deep, we need to calculate its volume.
Here's how:
1. Understanding Volume
Volume is the amount of space a three-dimensional object occupies. For a rectangular box, it's calculated by multiplying its length, width, and depth.
2. Applying the Formula
- Length: 12 inches
- Width: 12 inches
- Depth: 4 inches
Volume = Length x Width x Depth
Volume = 12 inches x 12 inches x 4 inches
Volume = 576 cubic inches
Therefore, a junction box measuring 12 × 12 × 4 inches deep contains 576 cubic inches.
