Question

what is the surface area and volume of the biggest Spear made out of cube by side 42 cm? please tell answer step by step.
By the way the answer is
surface area =1764π cm^2,
volume = 12348π cm^3.​

Answer 1

Answer:

pls Mark me as brainleist

Step-by-step explanation:

The diameter of Biggest sphere will be equal to side of square 

⟹ radius =24a=2a

Surface area of sphere is 4πr2=4π(2a)2=16πa2

Answer 2

Answer:

Yes the answer you mentioned is correct

Step-by-step explanation:

Surface area of sphere

$4\pi \times {r}^{2}$

Here r = 42/ 2 = 24

Area = 24*24*4*pie

$surface \: area \: = 1764\pi$

And volume =

$4 \div 3 \times \pi {r}^{3}$

Hence volume of the given sphere is

4/3 * 24*24*24*pie

So,

$volume = 12348\pi$
