Jerry wants to wrap a present in a box for his mother. The box measures 10 cm wide, 4 cm high, and 17 cm long. How much wrapping paper will Jerry need to wrap the present? (1 point) surface area= cm2

1 answer

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

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

where \( l \) is the length, \( w \) is the width, and \( h \) is the height of the box. Given:

  • Length \( l = 17 \) cm
  • Width \( w = 10 \) cm
  • Height \( h = 4 \) cm

Plugging in the values:

\[ \text{Surface Area} = 2(17 \times 10 + 17 \times 4 + 10 \times 4) \]

Calculating each term inside the parentheses:

  1. \( 17 \times 10 = 170 \)
  2. \( 17 \times 4 = 68 \)
  3. \( 10 \times 4 = 40 \)

Now we sum these products:

\[ 170 + 68 + 40 = 278 \]

Now multiply by 2 to find the total surface area:

\[ \text{Surface Area} = 2 \times 278 = 556 , \text{cm}^2 \]

Thus, the total amount of wrapping paper Jerry will need to wrap the present is

\[ \boxed{556} , \text{cm}^2 \]
