Answer:
![310.35cm^3](https://tex.z-dn.net/?f=310.35cm%5E3)
Step-by-step explanation:
Volume of a Prism=Base Area X Height
The base is an equilateral triangle of side 8cm.
We can find the area of the triangle using Herons Formula.
Given a triangle with sides a,b and c
Area![\sqrt{s(s-a)(s-b)(s-c)}](https://tex.z-dn.net/?f=%5Csqrt%7Bs%28s-a%29%28s-b%29%28s-c%29%7D)
Where:
Semiperimeter, s![=\frac{a+b+c}{2}](https://tex.z-dn.net/?f=%3D%5Cfrac%7Ba%2Bb%2Bc%7D%7B2%7D)
The sides are of length 8cm, 8cm and 8cm.
Therefore:
s![=\frac{8+8+8}{2}=12cm](https://tex.z-dn.net/?f=%3D%5Cfrac%7B8%2B8%2B8%7D%7B2%7D%3D12cm)
Area![=\sqrt{12(12-8)(12-8)(12-8)}=27.71cm^2](https://tex.z-dn.net/?f=%3D%5Csqrt%7B12%2812-8%29%2812-8%29%2812-8%29%7D%3D27.71cm%5E2)
Since Base Area =27.71cm^2
Volume=27.71*11.2
![=310.35cm^3](https://tex.z-dn.net/?f=%3D310.35cm%5E3)
Answer:
If two ratios are equivalent to each other, then they are said to be in proportion. For example, the ratios 1:2, 2:4, and 3:6 are equivalent ratios.
Step-by-step explanation:
Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional.
