Jerry wants to wrap a present in a box for his mother. The box measure 10 cm wide, 4 cm high, and 17 cm long. How much wrapping paper will jerry need to wrap the present?
To calculate the amount of wrapping paper Jerry will need, we need to find the surface area of the box.
First, let's find the surface area of the top and bottom of the box:
Top and bottom = 2 * (10 cm * 17 cm) = 2 * 170 cm^2 = 340 cm^2
Next, let's find the surface area of the sides of the box:
Sides = 2 * (10 cm * 4 cm) + 2 * (17 cm * 4 cm) = 2 * 40 cm^2 + 2 * 68 cm^2 = 80 cm^2 + 136 cm^2 = 216 cm^2
Now, let's add the surface area of the top and bottom to the surface area of the sides to find the total amount of wrapping paper needed:
Total wrapping paper = Top and bottom + Sides = 340 cm^2 + 216 cm^2 = 556 cm^2
Therefore, Jerry will need 556 cm^2 of wrapping paper to wrap the present.
