The formula for finding the surface area of a rectangular prism is 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height.
Using the measurements given:
- 2 rectangles with measurements 15 inches by 12 inches: 2(15)(12) = 360 in^2
- 2 rectangles with measurements 12 inches by 6 inches: 2(12)(6) = 144 in^2
- 2 rectangles with measurements 15 inches by 6 inches: 2(15)(6) = 180 in^2
Adding these three values together: 360 + 144 + 180 = 684 in^2
Therefore, the surface area of the rectangular prism created by this net is 684 in^2.
The net of a rectangular prism shows two rectangles each with measurements 15 inches by 12 inches, two other rectangles with measurements 12 inches by 6 inches, and two more rectangles with measurements 15 inches by 6 inches. What is the surface area of the rectangular prism this net creates in square inches? (1 point)
