Question

A glass is 2/3 full. Then 40cm3 (cubed) of orange juice is poured in. The glass is now 4/5 full.
What is the total volume of the glass?

Answer 1

Answer:

The total volume of the glass is 300cm³

Step-by-step explanation:

Let the volume of the glass be V.

The amount of glass filled intially = (2÷3)×volume.

The amount of glass filled after 40 cm³ of orange is poured = (4÷5)×volume

Change in volume =  (4÷5)- (2÷3)

                               =(2÷15)×V

Change in volume = 40

  (2÷15)×V= 40

    V= 20×15

    V= 300 cm³

The total volume of the glass is 300cm³
