Answer:
Height = 18.2 inches
Step-by-step explanation:
15 gallons = 3,465 cubic inches
Length of the rectangular prism = 20 inches
Width of the rectangular prism = 10 inches
Height of the rectangular prism = x inches
Volume of the rectangular prism = 3,645 cubic inches
Volume of the rectangular prism = length × width × height
3,645 = 20 × 10 × x
3,645 = 200x
Divide both sides by 200
3,645 / 200 = x
18.225 = x
To the nearest tenth of an inch
x= 18.2 inches
Therefore,
The rectangular prism is 18.2 inches high
