Answer:
The answer to your question is 24 cm³
Step-by-step explanation:
Data
Initial volume = 2/5
Additional volume = 42 cm³
Final volume = 4/7
the total volume of the glass = ?
Process
1.- Write a proportion to help you solve the problem
42 cm³ -------------------- 4/7 of the total
x ------------------- 7/7
2.- Solve the proportion
x = (7/7 x 42) / 4/7
3.- Simplification
x = 42 / 4/7
x = 168/7
x = 24 cm³
if you show the triangle on the graph i can figure it out, or give me the coordinates of the original triangle, can't really do it without those things

➷ Volume = height x base x width
Volume = 4 x 4 x 4
Volume = 64
The volume is 64cm^2
