The difference between 98 and 78 times 11
the quantity 98 minus 78 times 11
Answer:
$1,194
Step-by-step explanation:
The area of the parking lot is 253.5(176.5) which equals 44,472.75. You then divide 44,472.75 by 4000 to see how many gallons you need to cover the parking lot. The answer to that was about 11.2 and since you can only purchase full drums you have to round it up to 12 to have enough. Finally, you multiply 12 by 99.50 and get your answer.
4x300+4x60+4x2
1200+240+8
1448
Total SA = top + bottom + 2 (short side) + 2 (long side)
top = bottom = 5×3 = 15
short side = 7×3 = 21
long side = 7×5 = 35
SA = 2 (15) + 2 (21) + 2 (35) = 30+42+70 = 142
So 142 - 121 = 21, so the missing face is a short side of 7×3
