The surface area of a solid cube is 1800cm2.Work out the volume.Give your answer as a surd in its simplest form.

21, 30 and 2.

Step-by-step explanation:

To find the mean you need to add up all the ages and divide them by however many there are.

In this case it's 27 + 13 + 16 +20 +41 + 9 = 126

126 divided by 6 = 21 so that's your answer.

Since another patient arrived we need to do 126 + 84 = 210. We need to remember that we have 7 patients now so we are going to do,

210 divided by 7 = 30.

Lastly, out of all the ages only 2 are over 30. The patient who is 41 and the new patient who is 84.

Hope that helps. x
