Serggg [28]
If the width of the cardboard = x cm then its length is given by x + 8 cm.
Then the length of the box will be x + 8 - 2(2) =  x + 4
and the width = x - 2(2) = x - 4 cm The height is 2 cm 

Volume = h*w*l = 2(x - 4)(x + 4) = 256
2(x^2 - 16) = 256
x^2 - 16 = 128
x^2  = 144 
x = 12 cm 

Dimensions of the box are:-

length =  12 + 4 =  16cm
width = 12 - 4 = 8 cm
height = 2 cm

The petrol tank at the local service station has a capacity of 6000L. It is 66.06 percent full. How many litres of petrol are ne
Rina8888 [55]


Since the tank is 66.06% full, it is (100 - 66.06) = 33.94% empty.

Its capacity is 6,000L.  So, in order to fill it to capacity, the service station
must order  33.94% of 6,000L .

               33.94% = 0.3394
               "of" means "times"

0.3394 x 6,000L = <em>2,036.4 liters</em> needed, to fill the tank to the rim.
