how do you round to the nearest cubic

I'm assuming that you mean "Cubic Unit". I will use inches in this example, but this will work with other units as well.

Let's say that the volume of a figure was 124.86 cubic inches.

Rounding to the nearest cubic inch is the same thing as rounding to the nearest whole number.

Locate the 'ones' place:

124.86

Check next door:

124.86

If the next door number is greater than or equal to 5, then we round up. If it's less than 5, we round down.

8 is greater then 5. Therefore, we would round up.

So, 124.86 cubic inches to the nearest cubic inch is 125 in³.

124.86in³ ≈ 125in³

n/4 - 3

Step-by-step explanation:

Let's "break" the statement in simpler parts:

First, we start with a number n.

Now, we need to find one fourth of that number, that is:

(1/4)*n = n/4

And finally, we need to subtract 3 from that, then we get:

n/4 - 3

So the statement:

"Emily is thinking of a number she calls it n then she finds 1 fourth of it and subtracts 3"

Can be written as:

n/4 - 3
