Answer: Total area of the given prism is (104 + 16√13) Square inches.
Step-by-step explanation:
By the given diagram,
In the right triangular prism,
The sides of the base ( right triangle ) are 4 inches and 6 inches,
We have to finds : T.A. ( the total area of the prism )
Thus, the total base area of the prism = 2 × ( Area of triangle having base 4 inches and height 6 inches )
= 2× ( 1/2 × 4 × 6 )
= 4 × 6
= 24 square inches,
Let the hypotenuse of the triangles having sides 4 and 6 is x inches, ( shown in the diagram )
Thus, by the given diagram,
Now, the total lateral area of the prism,
= 8×2√13 + 8×4 + 8×6
= 16√13 + 32 + 48
= (16√13 + 80) square inches,
Since, the total area of the given prism (T.A.) = Total base area of the prism(B.A.) + Total lateral area ( L.A.)
= 24 + 16√13 + 80
= (104 + 16√13) Square inches.
