Answer:
The surface area is 40
Step-by-step explanation:
It is 40 because you have to find the area of each face so you would do 3*4 which equals 12 and since there is 4 of the triangles you do 12*4 which is 48 but when it's a triangle you have to cut it in half so it would really be 24.
Then for the square on the bottom you would do 4*4 which is 16 and then you would add the totals to get 40.
Answer:
B. the two triangles are congruent because of SSS postulate
The real engine is 65.25 feet long
<h3>How to determine the length?</h3>
The scale is given as:
Scale = 87 feet to 1 foot
The scale length is given as
Scale length = 9 inches
Convert inches to feet
Scale length = 9/12 feet
The actual length is then calculated as:
Actual = 87 * 9/12 feet
Evaluate
Actual = 65.25 feet
Hence, the real engine is 65.25 feet long
