The problem is that 7^2 is 7*7, and the same for 8^2. The right answer is the square root of 15, or 3.87
Okay, so there's a number rounded to the nearest million, in this case 2 million. So this tells me that the number of visitors is between 1,500,000 and 2,499,999. The reason why 1,499,999 doesn't count is because the hundred thousands digit is not 5 or above, so it doesn't count. It would round down to 1 million, not 2 million. The reason why 2,500,000 doesn't count, is because the hundred thousands digit is 5, so that rounds to 3 million, not 2 million. The greatest number of visitors that visited the aquarium has to be 2,499,999, because that's one digit away from 2.5 million, and the hundred thousands digit is a 4, not 5. The answer is 2,499,999
Step-by-step explanation:
How are we supposed to find volume if you don't enter the other elements I.e width, length and height?
But just in case the formulae for finding volume is to multiply is elements. So to find volume multiply is width, length and height.
