The net of a rectangle prism is shown. What is the surface area of the rectangular prism? ( 3 in, 4 in, 9 in. )
The net of a rectangular prism consists of 6 faces, where each face is a rectangle.
The dimensions given are:
Length = 3 in
Width = 4 in
Height = 9 in
The surface area of a rectangular prism is given by the formula:
Surface Area = 2lw + 2lh + 2wh
Plugging in the values:
Surface Area = 2(3)(4) + 2(3)(9) + 2(4)(9)
Surface Area = 24 + 54 + 72
Surface Area = 150 square inches
Therefore, the surface area of the rectangular prism is 150 square inches.
