Trudy is starting a science experiment. She will grow salt crystals in a clear plastic box. The inside of Trudy's box is 9 inches long and 5 inches wide. Trudy pours salt water into the box to a height of 4 inches. What is the volume of salt water in the box?

Answer 1

The volume of the salt water in the box can be found by multiplying the length, width, and height of the water:

Volume = length x width x height

Volume = 9 inches x 5 inches x 4 inches

Volume = 180 cubic inches

Therefore, the volume of salt water in the box is 180 cubic inches.
