Step-by-step explanation:
Given

See attachment for the base of the prism
Required
The volume of the box
From the attachment, we have:
-- side length of the octagon
The area is then calculated as:

So, we have:



Evaluate the square root



The volume is then calculated as:


Answer:
(33+7)-(15/3) = 35
Step-by-step explanation:
Answer:
x = 5
Step-by-step explanation:
(2x - 1) / 9 = 3x / 15
Cross multiply
9(3x) = 15(2x - 1)
Distributive
27x = 30x - 15
Subtract 30x from both sides
-3x = -15
Divide by -3 on both sides
x = 5
No, 1/18 is the simplest form. :)
