up to the height of 40 cm. How much more water is needed to completely fill the box?
​

Answer 1

Answer:

$108000cm^3$

Step-by-step explanation:

Length of the Box = 30 cm

Width(Breadth) of the Box = 30 cm

Height of the Box = 1m 60cm = 100cm + 60cm = 160 cm

Capacity of the Box = Volume of the Box

$Volume~of~Cuboid=l*b*h\\\\Volume~of~Cuboid=30*30*160\\\\Volume~of~Cuboid=144000cm^3\\\\-----\\\\Volume~of~water~present~in~Box=30*30*40\\\\Volume~of~water~present~in~Box=36000cm^3$

To find How much water more is needed to completely fill the box :

$Volume~of~empty~Box=\\Total~Volume~of~Box-Volume~of~water~in~Box\\\\Volume~of~empty~Box=144000-36000\\\\Volume~of~empty~Box=108000cm^3$

∴ 108000 cm³ more water is needed to completely fill the Box.
