Answer:

The answer is 61.4 L

Step-by-step explanation:

Using the formula of cuboid, V = l×b×h, to find the total amount of water contained :

l = 120cm

b = 40cm

h = 15cm

V = 15×120×40

= 72 000cm³

= 72 L

It is given that she uses 10.6L for shower. Then calculate the remaining water by substracting 10.6L from the original amount of water :

remaining = 72 - 10.6

= 61.4 L

Answer:

93.8 Litres

Step-by-step explanation:

Shower:

10.6 litres water per minute for 7 minutes

Water Used = 10.6 x 7 = 74.2 Litres

Bath:

1 cuboid bath

The volume of the cuboid is:

120 x 35 x 40 = 168,000 cm³

168,000/1000 = 168 Litres

She saves:

168 - 74.2 = 93.8 Litres
