8. A bath tub is 78 cm long, 42 cm broad and 35 cm high. How many litres
it hold?​

Answer 1

Answer:

$\huge\bold\red{114.6\:litres}$

Step-by-step explanation:

Given,

A bath tub having dimensions,

length, l = 78 cm

breadth, b = 42 cm

height, h = 35 cm

Now, to find the Litres it hold,

we have to find the volume of the tub.

Since, it is of cuboidal shape,

we have ,

Volume, v = lbh

$= > v =( 78 \times 42 \times 35 ) \: \: {cm}^{3} \\ \\ = > v = \: 114660 \: {cm}^{3}$

Now, we know that,

$1 \: {cm}^{3} = 1 \: ml \\ \\ = > 1 \: {cm}^{3} = \frac{1}{1000} \: l$

Therefore, to change the volume in litre, we have to divide it with 1000,

So, we get,

$v = \frac{114660}{1000} \: l \\ \\ = > v = 114.6 \: l$

Hence, the volume is 114.6 litres
