Answer:
Step-by-step explanation:
2 surfaces that are 5x7
2 surfaces that are 4x7
and the top and bottom that are 4x5
2*5*7 = 70
2*4*7 = 56
2*4*5 = 40
total surface is 166 
Answer:
b. 9h
Step-by-step explanation:
Volume of the cube = a*a*a
Volume of the cube = 3*3*h = 9h
But in reality for cube it should be 3*3*3= 27, because of the all edges of a cube are equal.
Answer:
1 (-4,5), (-2,1) (2,2) (5,5)
2 (0,1) (-4,3) (-4,1)
Step-by-step explanation:
Using the pythagorean theorem: c^2 = a^2 + b^2
c = 12 feet
a = 3 feet
b = x feet
12^2 = 3^2 + x^2
144 = 9 + x^2
144 - 9 = x^2
135 = x^2
x = 11.6 feet
Therefore, the answer is B.
