The formula to find the volume of a prism is V=Bh (Volume = Base x height). Let's plug in the dimensions you were given:
V=Bh
V=(5)(10)
V=50 {tex] ft^{2} [/tex]
To find the new volume of the dilated prism, cube the dilated factor, then multiply by the volume you just found (old volume):
New Volume = (

)(Old Volume)
V = (

)³·50
V = (

V = 86.4
Answer:
69
Step-by-step explanation:
m1 = 180 - (180 - 39 - 30) = 180 - 111 = 69
Plug n = 1 into the expression 20-9n and we get
20-9n = 20-9*1 = 20-9 = 11
So 11 is the first term of the series that we add up. Therefore the answer must be choice C, which has 11 listed as the first term added
10.5 is the answer to your question
