Answer:

A  =  532 ft^2 total

Step-by-step explanation:

There are 3 sets of 2 identical areas:  2 top/bottom, 2 sides, 2 ends.

Suppose the length is 14 ft, the width 7 ft and the height 8 ft.

A =  2 * (base area) + 2 * (end area) + 2 (side area)

   = 2 * (98 ft^2)       + 2 * (56 ft^2)     + 2 (112 ft^2)

   = 196 ft^2 + 112 ft^2 + 224 ft^2

A  =  532 ft^2 total

Your car gets about 20 miles per gallon. You are planning to drive to
igor_vitrenko [27]

Answer:

42.5 or 43

Step-by-step explanation:

Since you need to travel 850 miles, and you can travel 20 miles per gallon, you should divide 850 by 20 to get the number of gas cans needed. In doing so, you get 42.5 gas cans, but since it may be asking for whole cans rather than part of a gas can, you might want to write 43 instead. If you were to round down to 42, you would not have enough gas to finish the trip, so you should round up to 43. So, it is up to you if you want to write 42.5 or 43.

Hope this helped somewhat! ;(

Paul [167]
So basically it takes 10 people to paint a whole building. Forget about the 5 days. That's just there to confuse you. You have to first find out how much of a building can one person paint so, 1/10. So that means that 7 people can paint 7/10 of a building in 5 days
