Answer:
x = ![\sqrt{84}](https://tex.z-dn.net/?f=%5Csqrt%7B84%7D)
Step-by-step explanation:
According to Pythagorean Theorem, the square value of hypotenuse is equal to sum of square value of two legs:
x^2 + 4^2 = 10^2
x^2 + 16 = 100 subtract 16 from both side
x^2 = 84 find the root of both sides
x = ![\sqrt{84}](https://tex.z-dn.net/?f=%5Csqrt%7B84%7D)
Answer: ![1,542,682\ cm^3](https://tex.z-dn.net/?f=1%2C542%2C682%5C%20cm%5E3)
Step-by-step explanation:
Given
The ratio of two similar figures is 169:289
Suppose, their length ratio is x:y
![\therefore \dfrac{x^2}{y^2}=\dfrac{169}{289}\\\\\Rightarrow \dfrac{x}{y}=\dfrac{13}{17}](https://tex.z-dn.net/?f=%5Ctherefore%20%5Cdfrac%7Bx%5E2%7D%7By%5E2%7D%3D%5Cdfrac%7B169%7D%7B289%7D%5C%5C%5C%5C%5CRightarrow%20%5Cdfrac%7Bx%7D%7By%7D%3D%5Cdfrac%7B13%7D%7B17%7D)
Similarly, cube of the ratio is equal to the volume ratio
![\Rightarrow \left(\dfrac{13}{17}\right)^3=\dfrac{689,858}{V}\\\\\Rightarrow V=689,858\times \dfrac{17^3}{13^3}\\\\\Rightarrow V=314\times 17^3\\\\\Rightarrow V=1,542,682\ cm^3](https://tex.z-dn.net/?f=%5CRightarrow%20%5Cleft%28%5Cdfrac%7B13%7D%7B17%7D%5Cright%29%5E3%3D%5Cdfrac%7B689%2C858%7D%7BV%7D%5C%5C%5C%5C%5CRightarrow%20V%3D689%2C858%5Ctimes%20%5Cdfrac%7B17%5E3%7D%7B13%5E3%7D%5C%5C%5C%5C%5CRightarrow%20V%3D314%5Ctimes%2017%5E3%5C%5C%5C%5C%5CRightarrow%20V%3D1%2C542%2C682%5C%20cm%5E3)
Thus, the volume of the larger solid is ![1,542,682\ cm^3](https://tex.z-dn.net/?f=1%2C542%2C682%5C%20cm%5E3)
The area is 8 blocks it is 2*4=8
