Please help i am hopeless at maths!

A sample of contaminated urine was enumerated using a counting chamber (haemocytometer) and 220 bacterial cells were counted in the 25 small squares (each of a volume 2.5 x10-7 cm3)
Viable counts were carried out on the same culture using both the pour plate method (incorporating 1cm3 samples of a range of dilutions into the plate count agar plates) and the Miles and Misra spread plate method, where 0.02cm3 samples were spread on sectors of a plate count agar plate.

For the plate, count the average of triplicate samples was 178 colonies per plate of the 10-4 dilution.
For the Miles and Misra count the average of triplicate samples was 21.3 colonies per sector of the 10-4 dilution.

Calculate the total count and the viable pour plate and spread plate counts.

Thankyou any help is welcome!
