Given the volume of Wesley's cube = 8 cubic centimeters.

We know the formula for volume of cube is given as follows :-

Volume of cube = (side) x (side) x (side)

8 = (side)³

side = $\sqrt[3]{8} =\sqrt[3]{2*2*2} =2$

Hence, Wesley's cube dimensions are 2 centimeters.

The square must have side length as 2 centimeters.

If smallest square G represents 1 centimeters, then clearly it is H = 2 centimeters.

So, square H is the final answer.

(50 POINTS) What is the length of YZ in Triangle XYZ? Explain two different methods that could be used to find this length.

LenKa [72]

<h3>First Method:</h3>

<u>Using cosine rule</u>:

$\rightarrow \sf cos(30 ) = \dfrac{YZ}{12}$

$\rightarrow \sf YZ = 12cos(30 )$

$\rightarrow \sf YZ = 6\sqrt{3}$

$\rightarrow \sf YZ = 10.4$

<h3>Second Method:</h3>

<u>First find XY using sine rule</u>:

$\rightarrow \sf sin(30)=\dfrac{XY}{12}$

$\rightarrow \sf XY = 12sin(30)$

$\rightarrow \sf XY =6$

Then use Pythagoras Theorem:

⇒ XY² + YZ² = XZ²

⇒ (6)² + YZ² = 12²

⇒ YZ² = 144 - 36

⇒ YZ = √108

⇒ YZ = 6√3

⇒ YZ = 10.4
