How what size is the large block?
Convert the measurements of the large block to cm.
Then calculate the Volume of the large cube.
The answer will be in cubic cm. That is the number of 1 cm cubes.
Find the value of θ,
θ = arccos -8/9 = 152.734 deg
You can substitute this value for the requirement.
tan 152.734 = -0.51539
sin 152.734 = 0.45812
The area of the square would be greater. To get the area of a square you need to multiply the length and width of the square, therefore you would multiply 10x10 which comes out to be 100. The perimeter would only be 40.
Answer: 72 ft
Step-by-step explanation:
Given
The width of a post is 
Posts are separated by
chain
for 2 posts, length is 
for 3 posts, length is 
for 4 posts, it is 
i.e. 11 ft is adding on the addition of another post
for 7 posts it is 
Thus, the total length of the fence is
