Question 6(Multiple Choice Worth 3 points)

(05.06)Which net matches the solid figure shown below?

A rectangular prism with height of 9 centimeters, length of 7 centimeters, and a width of 2 centimeters.

A net is shown with 3 rectangles attached side by side all with width 9 centimeters and length 7 centimeters. Attached to the middle rectangle above is a rectangle with a length of 7 centimeters and a width of 2 centimeters. Attached to the middle rectangle underneath are 2 more rectangles with the same length and widths 9 centimeters and 2 centimeters.

Answer 2

A net is shown with 3 rectangles attached side by side all with width 2 centimeters. The length of the first and third rectangle is 9 centimeters and the middle is 7 centimeters. Attached to the middle rectangle below are 3 rectangles with a length of 7 centimeters. The width of these rectangles are 9 centimeters, 2 centimeters, and 9 centimeters.

Explanation:

The area of a rectangular prism is the area of 6 surfaces. That is, 3 pairs of surfaces. Each of the three pairs will have one of the sets of dimensions ...

• length × width
• length × height
• width × height

In order for a net to be a net useful for calculating the prism surface area, it must have 3 pairs of rectangles with these dimensions. The description above matches that requirement.

___

Please note that no two surfaces with the same pair of dimensions are adjacent.
