The surface area of the triangular prism is 2376 square ft option second is correct.
When a triangle is, stretch it out to produce a stack of triangles, one on top of the other. A triangular prism is a name given to this novel 3D object.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
As we know,
The surface area (rectangle) = Length×Width
[tex]\rm Surface \ Area (triangle) = \dfrac{1}{2}Base\times Height[/tex]
Rectangular side 1:
Length = 40 ft
Width = 24 ft
Surface Area = 40×24 = 960 squre ft
Rectangular side 2:
Length = 40 ft
Width = 15 ft
Surface Area = 40×15 = 600 square ft
Rectangular side 3:
Length = 40 ft
Width = 15 ft
Surface Area = 40×15 = 600 square ft
Triangular side 1:
Base = 24 ft
Height = 9 ft
Surface Area = (1/2)(24)(9) = 108 square ft
Triangular side 2:
Base = 24 ft
Height = 9 ft
Surface Area = (1/2)(24)(9) = 108 square ft
Adding all surface areas to find the surface area of the triangular prism:
= 960 + 600 + 600 + 108 + 108
Surface area = 2376 square ft
Thus, the surface area of the triangular prism is 2376 square ft option second is correct.
