Question 608260: Mr.Algebra baked a cake for the Midwest Mathematics Convention. He designed the cake in the shape of a big cube. As he was carrying the cake over to frost it, he dropped it in the vat of frosting. Amazingly, athe cake stayed in one piece, but all 6 sides were frosted. One mathematic suggested the cake be cut into cube shaped pieces, all the same size. That way, some people could have a piece with no frosting, 1 side frosted, 2 sides frosted, or 3 sides frosted. Another mathematician suggested, "Cut the cake so that the number of pieces with no frosting is eight times more than the number of pieces with 3 sides frosted. Then you will have the exact number of pieces of cake as there are mathemeticians in this room." Find out how many mathematicians were at the convention.

Question 608959: Could someone check my answer for this one-

The formula for measuring drag force on a car is Fd=1/2pv^2ACd where Fd is the drag force measured in Newtons, p is density, v is velocity, A is area and Cd is the drag coefficient. Assuming that all the factors are measured in SI units, what units should Cd have to make the formula dimensionally homogeneous?^
Fd=kgm/s^2
p=kg/m^3
v=m/s
A=m^2
Cd=?
Therefore kg*m/s^2 / 1/2*kg/m^3*m/s*m^2
Cancelling the kg and m^2 and m^3
Seem to leave m / s * 1/2
Does this mean Cd has no units or could I inverse 1/2 and 1/s to make m^s2
