Let's find the volume of the tank by l×w×h 10×3×7 30×7 210 ft³ So the volume of the water in the tank is 210 ft³. Now, since it is 62.4 pounds per cubic foot, we have to multiply. 62.4×210 13,104 The weight of the water in the tank is 13,104 lbs.
You do 5 times x and 5 times 4 and you’d end up with equation that says 5x-4=6. The you add 4 to both sides of the equation to cancel out the 4. Your equation should now say 5x=10. You divide both sides by 5 and you have your answer x=2
