Answer 1

To calculate the surface area of a box (rectangular prism), you can use the following formula:

\[
\text{Surface Area} = 2 \times (length \times width + length \times height + width \times height)
\]

Given:
- Width = 2.5 cm
- Length = 8 cm
- Height = 10 cm

Let's calculate it step by step.

1. Calculate each product:
- Length × Width = 8 cm × 2.5 cm = 20 cm²
- Length × Height = 8 cm × 10 cm = 80 cm²
- Width × Height = 2.5 cm × 10 cm = 25 cm²

2. Now, sum these areas:
- Total area = 20 cm² + 80 cm² + 25 cm² = 125 cm²

3. Then, multiply by 2 for the total surface area:
- Surface Area = 2 × 125 cm² = 250 cm²

So, the surface area of the box is **250 cm²**.
