9.66
^ This is the tenths place.
Look at the number after it, if it's 5 or more we round up, if it's 4 or less we round down.
The number is 6, so we round up to 9.7.

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)
The first one means 85 ÷ 5 = 17
The second one means 39 ÷ 3 = 13
The third one means 82 ÷ 2 = 41
The fourth one means 90 ÷ 6 = 15
The fifth one means 80 ÷ 8 = 10
