Karen found the dimensions of the tub filled with enough water to take a bath was 1.7 meters X 0.8 meters X 0.46 meters and that the shower uses 8 liters per minute. Karen figures a shower takes on average 24 minutes.

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

How much water does Karen use to take a bath?  

How much water does Karen use to take a shower?   

Solution

water was used when taking a bath by Karen (or) water does Karen use to take a bath = volume of water in the tub

we observe that tub is in the form of cuboid, whose

length (l) = 1.7m =170cm

breadth (b)= 0.8m =80cm

height (h)= 0.46m =46cm

volume of water = l.b.h

=170 . 80 . 46 cm³

= 625600 cm³

=625600 ml

=625.600 l

=625.6 l

water does Karen use to take a shower

shower uses water per minute = 8 liters

shower uses water per 24 minutes =24(8)liters

= 192 liters
