Answer:
Step-by-step explanation:
surface area of cuboid=2(l*b+b*h+h*l)
=2(15*15+15*7+7*15)
=2(225+105+105)
=2*435
=870
Answer:
35.4259791678 (or 35.426)
Step-by-step explanation:
Area is length x width. Since this is a square the length and the width are the same. So you would need to find the square root of 1255. (In simpler words, what times what is 1255?)
Answer:
31.62
Step-by-step explanation:
If we know it's a right triangle, we can use the Pythagorean Theorem to solve this problem.
10^2 + 30^2 = 1000
Find the square root of 1000 and get your answer of 31.62.
Hope this Helps!
Good Luck!

# of Bears = (3/8)×40 = 15
# of Dogs = (1/5)×40 = 8
# of Other Animals = 40 - 15 - 8 = 17
