Question

The length and breadth of a rectangular box are 90 cm and 40cm it contains 180 litres of water. How high is the water level

Answer 1

Answer:

Volume=180000cm3

h =v/lxb=18oooo/90x40

h = 50cm

height=50cm

Answer 2

Answer:

Height of water level is 50cm

Step-by-step explanation:

volume = Length X height X Breadth

given,

length = 90 cm

breadth = 40 cm

volume = 180 liters

convert into cm  ( 1 liter= 1000 cm)

so volume = 180 X 1000

                 = 180000 $cm^{3}$

now,

length X height X breadth = 180000

90 X height X 40   =  180000

Height = $\frac{180000}{90 X 40}$

height = 50 cm
