Answer:
216 sq m
Step-by-step explanation:
Surface area of triangular prism = bh + (s1 + s2 + s3)*L
Where,
b = 6 m
h = 8 m
s1 = 10 m
s2 = 8 m
s3 = 6 m
L = 7 m
Plug in the values
Surface area = 6*8 + (10 + 8 + 6)*7
Surface Area = 48 + 24*7 = 216 m²
Answer:
Step-by-step explanation:
The third side is thus, less than 14 + 11 = 25 cm. The side cannot be less than the difference of the two sides. Thus, the third side has to be more than 14 - 11 = 3 cm. So, the length of the third side could be any length greater than 3 cm and less than 25 cm.
The answer would be 52+n
n is for the missing number

The least will be one of the negative ones, -3 or -6/5. Since -6/5=-1.2, we see
-3 is the least
