Can somebody me. i have less then 10 mins to get the right answer

The stack is 3 inches high, and thus has four vertical rectangular areas 3 by 1 in^2 each, which constitutes a total vertical surface area of 4(3 in^2), or 12 in^2. Twice the area of the base is 2(1 in^2) = 2 in^2.

Combine 12 in^2 and 2 in^2:        14 in^2  is the total surface area of this 3-d object.

to find the unit price of an object, you divide the price by object. you are trying to find out how much an object cost per unit.

for instance, lets say you have 50lb of ice cream(object) that cost 8.00 dollars(price). to find the unit cost, we take the 8.00 and divide it by 50, which will give us .16 cents per pound. we can check this by multiplying .16 by 50 = 8.00

so

object = e2

price = d2

unit price = c2

formula for c2:

=d2 / e2

so in my example about ice cream, we would have the following.

e2 = 50

d2 = 8.00

c2 formula:

=d2 / e2
