Question

To make an open which tank a glass sheet of 2mm gauge is used. Outer Length, breadth and the height of the tank are 60.4 CM ,40.4 CM and 40.2 CM respectively . How much maximum volume of the water will be contained in it?

Please give reason.

Answer 1

Outer dimensions = 60.4 cm = 604 mm, 40.4 cm= 404 mm, 40.2 cm = 402 mm

Inner dimensions = 604-(2+2)mm = 600 mm = 60 cm

404-(2+2) = 400 mm = 40cm

Since. tank is open,

height = 402-2 mm = 400 mm= 40cm

Volume = l*b*h = 60*40*40 cm^3 = 96000cm^3 = Capacity of tank

Volume of water = 96000 cm^3= 96 litres

Answer 2

Answer: length, breadth and height reduces by 2 mm I.e the width of glass, so that inner tank length is 60.2cm, breadth is 40.2cm and height is 40.0 cm. Since u have all values required to find the volume of a cuboid shaped fish tank (no matter it is open or closed tank when we need to find the inner volume, inner volume in the sense volume of cuboid)

Volume = 60.2×40.2×40 cub.cm

= 96801.6 cub.cm
