A) A solid cubical block is 12 cm long, find its volum b) A cubical water tank is 80 cm broad.
(i) Find the volume of the tank
(ii) How many c. c. of water does it hold?
(iii) If 1000cm = 1 litre, how many litres of water
aa) If the volume of a cube is 729cm, find its length
b) The capacity of a cubical water tank is 216000cm
(i) What is the volume of the tank?
(ii) How high is the tank?
a) Test whether these numbers are perfect cubes or
(i) 192
(ii) 343
(ii) 500​

step by step solution :

step   1   :

1.1     4 = 22

(4)3 = (22)3 = 26

equation at the end of step   1   :

  ((23) • 26)2

step   2   :

equation at the end of step   2   :

  (23 • 26)2

step   3   :

final result :

  218

ιт ιѕ (9χ^5+10)(81χ^10-90χ^5+100)

step-by-step explanation:

нσρє ι ¢συℓ∂ нєℓρ уσυ συт тσ∂α

since no one answered yet i will give it a shot, not completely sure tho.

i think it should be y=cos(x+2pi), (third answer, answer c)

good luck.
