Given:
A prism with height 5 cm and equilateral triangular base with side 2 cm.
To find:
The total surface area of the prism.
Solution:
Area of an equilateral triangle is:

Where, a is the side length.
Putting
, we get




The base and top of the prism are congruent so their area must be equal.
The lateral surface area of the prism is:

Where, P is the perimeter of the base and h is the height of the prism.
The lateral surface area of the prism is:



Now, the total surface area is the sum of areas of bases and lateral surface area.




Therefore, the total surface area is 33.46 cm².
I think the answer is J

Total distance the rover need to travel is
.
<u>Step-by-step explanation:</u>
We have , Garne Problem med . A rover needs to travel mile to reach its destination traveled mile. a rover needs to travel 5/8 mile to reach its destination it has already travel 3/8 miles . We need to find that how much farther does the rover need to travel , Let's do it step by step:
First , rover has already traveled 3/8 miles , Let total distance to be traveled by rover is D :
⇒
, where d is distance left to cover .
Now, rover need to travel 5/8 miles more to reach destination :
⇒
, where d is distance left to cover , So
⇒
⇒ 
⇒ 
⇒ 
⇒ 
∴ Total distance the rover need to travel is
.
