Abathtub is in the shape of a rectangular prism. its dimensions are 5 feet by 3 feet by 18 inches. the bath tub is 3/4 full of water and drains at a rate of 1 cubic foot per min. about how long does it take for all the water to drain

Find the volume of the bath tub by multiplying all the dimensions together:

18 inches = 1.5 feet:

5 ft x 3 feet x 1.5 feet = 22.5 cubic feet.

The tub is 3/4 full so multiply the volume by 3/4 to find the amount of water in the tub:

22.5 x 3/4 = 16.875 cubic feet of water.

The tub drains at 1 cubic foot per minute, so it would take about 17 minutes to drain.    (16.875 rounded to the nearest whole minute).
