: this question is so hard can you help me pleeeeeeeaaaaaasssseeeeee? if you can this is how it looks like:
: A room has 525m(the area)of floor space. The volume of the room is 1425m. Calculate the height of the room.
: see what i mean?!? its confusing me!
....you're talking like a 7 year old!
First, the area is 525 square meters, not 525 meters.
The area is the length times the width; so that means the room
is probably 25 meters long by 21 meters wide:
25 meters times 21 meters = 525 SQUARE METERS : ok?
And the volume is 1425 cubic meters, not 1425 meters.
As you were told earlier, the volume is the area times the height;
SO: 525 times "the height" = 1425 CUBIC METERS : ok?
In algebra, you use a VARIABLE; let height = h;
SO: 525 times h = 1425; you'll see that as : 525h = 1425.
Now, calculate h; if you don't know how, well.....
