Question

Jayda wants to wrap a present for her friend. The box measures 10 cm wide, 4 cm high, and 17 cm long.

How much wrapping paper will Jayda need to wrap the present?



Surface Area formula: 2lw + 2wh + 2lh

(1 point)

Answer 1

To calculate the surface area of the box, we can use the surface area formula for a rectangular prism:

\[
\text{Surface Area} = 2lw + 2wh + 2lh
\]

where:
- \( l \) is the length,
- \( w \) is the width,
- \( h \) is the height.

Given:
- Length (\( l \)) = 17 cm
- Width (\( w \)) = 10 cm
- Height (\( h \)) = 4 cm

Now, let's plug in the values into the formula:

1. Calculate \( 2lw = 2 \times 17 \times 10 = 340 \) cm²
2. Calculate \( 2wh = 2 \times 10 \times 4 = 80 \) cm²
3. Calculate \( 2lh = 2 \times 17 \times 4 = 136 \) cm²

Now, add these areas together:

\[
\text{Surface Area} = 340 + 80 + 136 = 556 \text{ cm}^2
\]

Therefore, Jayda will need **556 cm²** of wrapping paper to wrap the present.
