Question

What is the approximate length of y? round to the nearest tenth of an inch. 1.4 in. 2.0 in. 2.8 in. 3.5 in.

Answer 1

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
