What is the surface area of a cube that has sides of length 2cm?
The formula for area which is(Length x Width)times the number of faces on a cube (6). So,(Length x Width) x 6.In the case of side with length 2 it would be2 x 2 x 6Giving us24cm^2
Are 224 and 243 relatively prime?
Oh honey, no. 224 and 243 are not relatively prime. They have a common factor of 1, which means they are as related as cousins at a family reunion. So, no need to waste your time trying to find a common ground for these two, they're just not that into each other.
How do you find the answer of fractions with different denomators?
Well first of all you find the least common multiple of the denominatorsex:3/5+ 2/9List 5's multiples5: 10 15 20 25 30 35 40 45 50 55 60 65 70Then list 9's multiples9: 18 27 36 45 54 63 72 81 90Then what is the lowest number in the list that they have in common?45!So rename the denominators so that they say /45Then what?You find out what you multiply the first denominator by to get the new denominators5 X 9 = 459 X 5 = 45 (because that's just how it is)So then you have to multiply the numerator by the same number as you multiplied the denominatorSo it would be3 X 9 = 27 So the first fraction would be 27/45and then it would be2 X 5 = 10 So the second fraction would be 10/45THEN ADD!27/45 + 10/45 = 37/45
