Question

A rectangular tank can hold k liters of water. how many liters of water can tank hold if all dimensions double.

Answer 1

Hey.

let dimensions of the tank be x,y,z
so, amount of water it can hold = volume of tank =xyz =k liters

if all dimensions get doubled it will become= 2x,2y,2z.
so, new volume= 2x×2y×2z=8xyz=8k..... {as xyz=k}

so, capacity will become 8 times of the previous capacity if all dimension gets doubled.

Thanks.
