Answer:
65.4 cm²
Step-by-step explanation:
The volume of a cuboid is calculated by multiplying the length, base, and height together. Since a cube has equal sides, the formula for the volume of a cuboid can be simplified as shown below.
Volume of cube
= side ×side ×side
= side³
Given that the volume is 36 cm³, let's find the length of each side.
side³= 36
Cube root both sides:
side=![\sqrt[3]{36}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B36%7D)
Total surface area of a cube is the sum of the surface areas of its 6 identical square faces.
Area of a square
= side ×side
= side²
Surface area of 1 face= ![(\sqrt[3]{36})^2](https://tex.z-dn.net/?f=%28%5Csqrt%5B3%5D%7B36%7D%29%5E2)
Total surface area
= ![6(\sqrt[3]{36} )^2](https://tex.z-dn.net/?f=6%28%5Csqrt%5B3%5D%7B36%7D%20%29%5E2)
= 65.416 (5 s.f.)
= 65.4 cm² (nearest tenth)

To learn more about surface area of cube, do check out the following!
Angle R is an inscribed angle. By the inscribed angle theorem, angle O (which is a central angle corresponding to the same arc as angle R) will be double that of angle R.
So in short,
(central angle O) = 2*(inscribed angle R)
(central angle O) = 2*(23)
(central angle O) = 46 degrees
The final answer is 46 degrees
I got 23 u might want to check it tho
U + v = {-3 + -3, -5 + 1} = <span> {-6 , -4}
</span>u + v = <span> {-6 , -4} </span>
The answers would be E,C,B. Hope this helped out it might not be right but trying my best to help out.
