A household aquarium tank in the shape of a rectangular prism has a base length of 24 inches (in) and a base width of 15in. The height of the water is 12 in above the base. During cleaning, 900 cubic inches of water is removed. What is the absolute value of the change in the height of the water in inches?
Q. A household aquarium tank in the shape of a rectangular prism has a base length of 24 inches (in) and a base width of 15in. The height of the water is 12 in above the base. During cleaning, 900 cubic inches of water is removed. What is the absolute value of the change in the height of the water in inches?
Calculate Initial Volume: Calculate the volume of water in the tank before removing any water.The volume of a rectangular prism is given by the formula: Volume = length × width × height.Here, the length is 24 inches, the width is 15 inches, and the height of the water is 12 inches.So, Volume = 24 in ×15 in ×12 in.
Find New Volume: Perform the multiplication to find the initial volume.Volume = 24in×15in×12in=4320cubic inches.This is the volume of water in the tank before any water is removed.
Calculate New Height: Subtract the volume of water removed from the initial volume.We know that 900 cubic inches of water is removed from the tank.So, the new volume of water in the tank is 4320 cubic inches −900 cubic inches.
Determine Change in Height: Perform the subtraction to find the new volume of water. New Volume = 4320 cubic inches - 900 cubic inches = 3420 cubic inches. This is the volume of water in the tank after removing 900 cubic inches.
Calculate Absolute Change: Calculate the new height of the water in the tank.We know the base area of the tank (length × width) is 24 in×15 in=360 square inches.To find the new height, we divide the new volume by the base area.New Height = New Volume / Base Area = 3420 cubic inches/360 square inchesPerform the division to find the new height of the water.New Height = 3420 cubic inches/360 square inches=9.5 inchesThis is the height of the water after removing 900 cubic inches.Calculate the change in the height of the water.The change in height is the original height minus the new height.Change in Height = Original Height - New Height = 12 inches−9.5 inchesPerform the subtraction to find the change in height.Change in Height = 12 inches−9.5 inches=2.5 inches.This is the change in the height of the water.
