Question

What is the length of an edge of a cubical water tank of capacity 125 litres?

Answer 1

Answer:

1 litre = 1/1000 m³

125 L = 0.125 m³

volume = 0.125 = side³

side = 0.5 m

Answer 2

Answer:

50 cm

Step-by-step explanation:

First we will make all value equal

${1\:l} = {1000\:cm}^{3} </p><p>{125\:l}={125000\:cm}^{3}$

We are given with the volume of a cube

The formula for the volume of a cube is

${side}^{3} = volume \: of \: cube$

So by putting the value of volume we get

${side}^{3} = 125000 {cm} ^{3}\\ side = \sqrt[3]{125000 } \\ side = 50\: cm$
