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

Question

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



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


(1 point)
Jayda will need
cm² of wrapping paper

Answer 1

To calculate the surface area of the box, we can use the formula:

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

Here:

• \( l \) (length) = 17 cm
• \( w \) (width) = 10 cm
• \( h \) (height) = 4 cm

Now, we can plug in the values:

1. Calculate \( 2lw \): \[ 2lw = 2 \times 17 \times 10 = 340 , \text{cm}^2 \]

2. Calculate \( 2wh \): \[ 2wh = 2 \times 10 \times 4 = 80 , \text{cm}^2 \]

3. Calculate \( 2lh \): \[ 2lh = 2 \times 17 \times 4 = 136 , \text{cm}^2 \]

Now, adding all these areas together:

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

Thus, Jayda will need 556 cm² of wrapping paper.
