Question

if a rectangular shaped tank has dimensions are 10m, 8m , 6m and contains water up to 3m. How much more water can be filled .

Answer 1

the height remained to be filled= 6-3=3m
then volume required to fill remaining= 10*8*3=240 m3

Answer 2

dimension=10m,8m,6m
and already contains water upto 3m
then,
volume of cuboid=lxbxh
=10x8x6
=480cm^3
=4.8m

therefore,
4.8m-3m
=1.8m

So, 1.8m more water can be filled.
