Question

Julia wanted to find out how much water was used when taking a bath, and when taking a shower.

Julia found the dimensions of the tub filled with enough water to take a bath was 1.5 meters x 1.1 meters x 0.46 meters, and that the shower uses 8.25 liters per minute.

Julia figures a shower takes on average 25 minutes.

Round answers to the nearest 10th of a liter.   1cc=1mL

How much water does Julia use to take a bath?__________ _____________

How much water does Julia use to take a shower? ____________ __________

Explanation / Answer

a) Dimension of tub = 1.5 m x 1.1 m x 0.46

volume of water in tub = l x b x h = 1.5 x 1.1 x 0.46 = 0.759 cubic meter

but 1 cubic meter = 1000 liter

So volume of tub in liter = 0.759 x 1000 L = 759 L

(b) since quantity of water used by shower per min = 8.25 L

But she take 25 min to bath, so

quantity of water used by shower in 25 min = 25 min x 8.25 L / min

   = 206.25 L
