9 of 9 A glass is į full. Then 75cm of orange juice is poured in.
The glass is now å full. What is the total volume of the glass?

180 cm³

Step-by-step explanation:

A glass is 1/3 full. Then 75cm³ of orange juice is poured in. The glass is now 3/4 full. What is the total volume of the glass?

Let

x = total volume of the glass

1/3x + 75 = 3/4x

75 = 3/4x - 1/3x

75 = 9x-4x/12

75 = 5/12x

x = 75 ÷ 5/12

x = 75 × 12/5

= 900/5

= 180 cm³

x = 180 cm³
