Hello there! So a cube has side lengths that are all equal and the formula for volume is l * w * h. If you raise the answer choices to the 3rd power, you see that 9³ is equivalent to 729, which is the volume we're looking for. The length of the side of the cube is 9 ft. The answer is B: 9 ft.

MARK ME BRAINLIEST!! THANKS BOO!!!!!!!!!!!
Step-by-step explanation:
Let x = Initial Price
If we increase x by 5%, we are adding 0.05x
Therefore, the new price = x + 0.05x = 1.05x
If the ticket has increased by £2.30, £2.30 is 5% of the initial price, or 0.05x
0.05x = 2.30
x = 2.30/0.05
x = 46
Therefore, the price of the ticket before the increase was £46
You can also check this backwards by doing 46*0.05 = 2.30
