6th grade Q3

You are wrapping a gift shaped like a rectangular prism. The gift’s dimensions are:

- Length: 10 inches
- Width: 10 inches
- Height: 5 inches

To know how much wrapping paper you need, find the surface area of the gift.

1. Find the area of each side:
- Top and bottom: These are each $10\text{ in}\times 10\text{ in}$
- Front and back: These are each $10\text{ in}\times 5\text{ in}$
- Left and right: These are each $10\text{ in}\times 5\text{ in}$

2. Calculate the area for each pair of sides and add them up.
Top and Bottom:

- Since there are two of these, you get:

Front and Back:

- Since there are two of these, you get:

Left and Right:

- Since there are two of these, we get:

4. Add all the areas:
