Answer: 604,375 = 600,000 + 4000 + 300 + 70 + 5.

Step-by-step explanation: I believe what's tripping you up is the fact that there are 6 digits in the number 604,375, and there are only 5 numbers to write out the actual number in equation form. The number in between 6 and 4 doesn't count, because if you write it out, it makes 00,000, so there's no point in adding 00,000 when it won't change the equation if you add it.

The question is asking to split the number and write out the digits from the greatest to the least amount of digits. For example, we're given 4,000, 300, and 5, which each are part of the number 604,375. 600,000 is the answer to the first blank and the blank between 300 and 5 is 70.

Let me know if this is right! :)

HELP! 6th-grade math PLEASE HELP!

Answers

first, find the area of prism ll by multiplying 5/2, 9/4, and 2

this will result in 45/4, or 11.25

now, you have to figure out how many small cubes will fit inside prism ll

we know that the side lengths of the small cubes are 1/4, and since cubes have equal side lengths, you can multiply 1/4, 1/4, and 1/4 to find the area

this will result in 1/64

divide the area of prism ll, 11.25, by the area of the small cubes, 1/64, to get 720

then, do the same thing for prism l

multiply 7/4, 3/2, and 5/4 to get 105/32

divide this by the previous 1/64 to get 210

lastly, to determine how many more small cubes can fit into prism ll, subtract 210 from 720

720-210=510

final answer: 510 cubes
