Answer:
3±95√3 is simplified as 167.5495 or - 161.5495
Step-by-step explanation:
Given expression;
3±95√3
This expression can be simplified as;
3±95√3 = 3 + 95√3 or 3 - 95√3
= 3 + 95(1.7321) or 3 - 95(1.7321)
= 3 + 164.5495 or 3 - 164.5495
= 167.5495 or - 161.5495
Therefore, 3±95√3 is simplified as 167.5495 or - 161.5495
You can just multiply the area of the base times the height. The base is a triangle which has an area of bh/2. If we let b=base, h=height (of the triangle base) and H=the height of the prism, then:
V=Hhb/2, in this case:
V=17*2*1/2
V=17m^3
