Question

a cubical box is filled in 1296 seconds at the rate of 1 litre per 6 seconds . calculate internal volume and length of the tank and also calculate the total internal surface area of the tank

Answer 1

ANSWER:----

{time taken to fill the tank = 1296 sec}

{capacity of tank = 1296/6 = 216 litres = 216 * 1000 cm3 = 216000 cm3}

{So, volume of tank = 216000 cm3

since the tank is cubical, length of tank = (216000)1/3 = 60 cm}

{Now, internal surface area of tank = 6 * 60 * 60 cm2 = 21600 cm2 }

Answer 2

Answer:

Interal volume= 216000, Length of side of tunk=60cm, Internal surface area= 21600

Step-by-step explanation:

{time taken to fill the tank = 1296 sec}

{capacity of tank = 1296/6 = 216 litres = 216 * 1000 cm3 = 216000 cm3}

{So, the volume of tank = 216000 cm3

since the tank is cubical, length of tank = (216000)1/3 = 60 cm}

{Now, internal surface area of tank = 6 * 60 * 60 cm2 = 21600 cm2 }
