Find the number of liters in 12.8 gal of gasoline. Round to the nearest hundredth
2 answers:
For this case we must perform a conversion of gallons to liters.
By definition, we have to:
1 gallon equals 3,78541 liters. By making a rule of three we have:
1 ----------------> 3.78541
12.8 -----------> x
Where "x" represents the amount of liters equivalent to 12.8 gallons.
Thus, 12.8 gallons of gasoline equals 48.453248 liters.
Rounding, we have: 48.45 liters
ANswer:
48.45 liters

Answer:
142.2 meters.
Step-by-step explanation:
We have been given that a box measures 70 cm X 36 cm X 12 cm is to be covered by a canvas.
Let us find total surface area of box using surface area formula of cuboid.
, where,
= Length of cuboid,
= Breadth of cuboid,
= Width of cuboid.
Therefore, the total surface area of box will be 7584 square cm.
To find the length of canvas that will cover 150 boxes, we will divide total surface area of 150 such boxes by width of canvass as total surface area of canvas will also be the same.
Let us convert the length of canvas into meters by dividing 14220 by 100 as 1 meter equals to 100 cm.
Therefore, 142.2 meters of canvas of width 80 cm required to cover 150 such boxes.
