Answer:
194 cm squared
Step-by-step explanation:
The prism is made of 5 shapes: 2 large rectangles, 2 triangles, and 1 medium rectangle.
To find the surface area, find the area of each surface and add them together.
2 large rectangles that measure 10 by 6. So the area is 60. For 2 it will be 2*60 = 120.
2 triangles that measure 4 by 6. So the area is 1/2*4*6 = 12. For 2 it will be 2*12 = 24.
1 medium triangle that measures 5 by 10. So the area is 50.
The total surface area is 120 + 24 + 50 = 194.

Answer:
31.4 in.
Step-by-step explanation:
The perimeter of a square is
P = 4s,
where s is the length of a side.
P = 4s
40 in. = 4s
s = 10 in.
Each side of the square measures 10 in.
The largest circle that fits inside a 10-square has a diameter of 10 inches.
For a circle, the circumference is
C = πd,
where d = diameter
C = πd
C = 3.14 * 10 in.
C = 31.4 in.
Assuming T, B and N are all on the same line, then we can say
BT + TN = BN
which is the segment addition postulate.
Subtract TN from both sides to get
BT + TN = BN
BT + TN - TN = BN - TN
BT = BN - TN
BN - TN = BT
Which is what choice C is saying. Therefore the answer is choice C.
