ANSWERS
In pounds: 535.9 lb
In tons: 0.27 tons
EXPLANATION
First, we have to convert 8.6 ft³ to gallons,
[tex]8.6ft^3\cdot\frac{7.48\text{ }gallons}{1ft^3}=64.328\text{ }gallons[/tex]
Then, convert from gallons to pounds,
[tex]64.328\text{ }gallons\cdot\frac{8.33\text{ }pounds}{1\text{ }gallon}=535.85224\text{ }pounds\approx535.9lb[/tex]
To find the weight in tons, we know that 1 ton is equivalent to 2000 pounds,
[tex]535.9\text{ }pounds\cdot\frac{1\text{ }ton}{2000\text{ }pound}=0.26795\text{ }tons\approx0.27\text{ }tons[/tex]
Hence, the weight in pounds is 535.9 pounds, rounded to the nearest tenth, and in tons is 0.27 tons, rounded to the nearest hundredth.
