Question

One cubic foot holds 7.48 gallons of​ water, and 1 gallon of water weighs 8.33 pounds. How much does 4.3 cubic feet of water weigh in​ pounds? In​ tons?

Answer 1

268 pounds

Explanation:

Two unit multipliers to be used for this unit conversion:

`(7.48 gallons)/(1ft^(3))` and
`(8.33 pounds)/(1 gallon)`

4.3 cubic feet =
`(4.3ft^(3))`×
`((7.48 gallons)/(1ft^(3)))` ×
`((8.33 pounds)/(1ft^(3)))`

The cubic feet units in the numerator and denominator will cancel each other out. The gallons units in the numerator and denominator will cancel each other out.
= 268 pounds of water (Rounded to 3 significant figures)
