The approximate length of "y" from the given diagram is 2.0inches
Volume of prisms
The formula for calculating the volume of a prism is expressed as:
V = lwh
l is the length
w is the width
h is the height
Given that V =4 cubic inches, hence:
4 = x * x* x
4 = x^3
x = ∛4
x = 1.587
Using the pythagoras theorem;
y^2 =1.587^2 +1.587^2
y^2 = 5.037
y = 2.0in
Hence the approximate length of "y" from the given diagram is 2.0inches
