Marc baked brownies in the brownie pan shown below. each day, he is going to eat 20 square centimeters of brownie from the pan.
for how many days does marc have brownies before they run out?

He will have brownies for 1189 days before he runs out

Step-by-step explanation:

So first we need to find the area of the brownie pan that the brownies are in and to do that the formula and length times width times height so we will multiply 20, 29 and 41 which gives us 23780 square centimeters.  That is how much total brownie Marc has and since he eats 20 square centimeters each day we will divide that number by 20 to figure out how many days he will have brownies for 23780/20=1189

I hope this helps and please don't hesitate to ask if there is anything still unclear!
