Transcribed Image Text:### Cereal Box Design Challenge
A cereal company wants to change the shape of its cereal box to attract the attention of shoppers. The original cereal box has dimensions of 8 inches x 3 inches x 11 inches. The new box the cereal company is considering would have dimensions of 10 inches x 10 inches x 3 inches.
#### A. Volume Comparison
**Question:** Which box holds more cereal? Show your work and explain your solution.
**Solution:**
To determine which box holds more cereal, we need to calculate the volume of each box.
**Original Box:**
- Dimensions: 8 in x 3 in x 11 in
- Volume = Length x Width x Height
- Volume = 8 in x 3 in x 11 in = 264 cubic inches
**New Box:**
- Dimensions: 10 in x 10 in x 3 in
- Volume = Length x Width x Height
- Volume = 10 in x 10 in x 3 in = 300 cubic inches
**Conclusion:**
The new box holds more cereal since 300 cubic inches > 264 cubic inches.
#### B. Surface Area Comparison
**Question:** Which box requires more material to make? Show your work and explain your solution.
**Solution:**
To determine which box requires more material to make, we need to calculate the surface area of each box.
**Original Box:**
- Length = 8 in, Width = 3 in, Height = 11 in
- Surface Area = 2(lw + lh + wh)
- Surface Area = 2(8 in x 3 in + 8 in x 11 in + 3 in x 11 in)
- Surface Area = 2(24 in² + 88 in² + 33 in²)
- Surface Area = 2(145 in²)
- Surface Area = 290 square inches
**New Box:**
- Length = 10 in, Width = 10 in, Height = 3 in
- Surface Area = 2(lw + lh + wh)
- Surface Area = 2(10 in x 10 in + 10 in x 3 in + 10 in x 3 in)
- Surface Area = 2(100 in² + 30 in² + 30 in²)
- Surface Area = 2(160 in²)
- Surface Area = 320 square inches
