Question

a vessels is in the shape of a cuboid which is 30 cm long and 25cm wide .how high must it be to hold 4.5 litres of water?

Answer 1

We have to find the Volume in this que. so,

Volume of Cuboid= lbh ( l= length b= base and h= height)

Here it is given :
l= 30 cm
b= 25 cm

So,
We know that 1 litre= 1000cm³ so
4.5 litres = 4500 cm ³

Now,
30×25×h= 4500cm³
750h= 4500
h= 4500-750
h= 3750 cm.

Answer 2

h=6cm this is correct answer above answer was calculations mistacks so that is wrong .
