To find the surface area of the rectangular prism, we can use nets. A net is a two-dimensional shape that can be folded to form a three-dimensional shape.
First, we need to identify the faces of the rectangular prism. A rectangular prism has 6 faces - 2 rectangular faces of dimensions 7 inches by 3 inches, 2 rectangular faces of dimensions 7 inches by 11 inches, and 2 rectangular faces of dimensions 3 inches by 11 inches.
Now, we can calculate the surface area of each face:
1. Face with dimensions 7 inches by 3 inches:
Surface area = 7 inches x 3 inches = 21 square inches
2. Face with dimensions 7 inches by 11 inches:
Surface area = 7 inches x 11 inches = 77 square inches
3. Face with dimensions 3 inches by 11 inches:
Surface area = 3 inches x 11 inches = 33 square inches
Next, we add up the surface areas of all 6 faces to get the total surface area of the rectangular prism:
Total surface area = 2(21) + 2(77) + 2(33) = 42 + 154 + 66 = 262 square inches
Therefore, the surface area of the rectangular prism with dimensions 7 inches by 3 inches x 11 inches is 262 square inches.
Apply the technique of using nets . What is the surface root of the rectangular person who dimensions measured 7 inches inches by 3 inches inches x 11 inches
