Answer: ![10\ cm^3](https://tex.z-dn.net/?f=10%5C%20cm%5E3)
Step-by-step explanation:
Given
The surface area of a rectangular prism is ![34\ cm^2](https://tex.z-dn.net/?f=34%5C%20cm%5E2)
Width of prism ![w=1\ cm](https://tex.z-dn.net/?f=w%3D1%5C%20cm)
Length of prism ![l=2\ cm](https://tex.z-dn.net/?f=l%3D2%5C%20cm)
height of prism ![h=x\ cm](https://tex.z-dn.net/?f=h%3Dx%5C%20cm)
Surface area is given by
![S.A.=2[lw+wh+hl]](https://tex.z-dn.net/?f=S.A.%3D2%5Blw%2Bwh%2Bhl%5D)
Put values
![34=2[2\times 1+1\times x+2x]\\17=2+3x\\15=3x\\x=5\ cm](https://tex.z-dn.net/?f=34%3D2%5B2%5Ctimes%201%2B1%5Ctimes%20x%2B2x%5D%5C%5C17%3D2%2B3x%5C%5C15%3D3x%5C%5Cx%3D5%5C%20cm)
Now, the volume of Prism is given by
![V=l\times w\times h](https://tex.z-dn.net/?f=V%3Dl%5Ctimes%20w%5Ctimes%20h)
![\Rightarrow V=2\times1\times 5=10\ cm^3](https://tex.z-dn.net/?f=%5CRightarrow%20V%3D2%5Ctimes1%5Ctimes%205%3D10%5C%20cm%5E3)
Answer:
2/5
Step-by-step explanation:
She completed 8 out of 20 so we divide 8 by 20
8/20 can be simplified if we divide both the numerator and denominator by 4
which equals 2/5
<span>1+3+5 = 9
72/9 = 8
1 x 8 = 8
3 x 8 = 24
5 x 8 = 40
</span><span>72 in a ratio of 1:3:5 = 8:24:40</span>
