Logan has two aquariums. One aquarium contains 2.5 cubic feet of water and the other contains 1.7 cubic feet of water. The water in the larger aquarium weighs 49.92 pounds more than the water in the smaller aquarium. Complete the equation with a variable on both sides to represent the situation. Use x to represent the weight of 1 cubic foot of water. Then find the weight of 1 cubic foot of water.
