Answer:
The total surface are is 252 sq. units.
Step-by-step explanation:
The right triangular sides have legs 8 units and 6 units and hypotenuse 10 units.
So, their area will be sq. units.
Now, the length of the prism is 8.5 units.
So, the area along the length will be = (8.5 × 6 + 8.5 × 8 + 8.5 × 10) = 204 sq. units.
Therefore, the total surface area is (48 + 204) = 252 sq. units. (Answer)
