The formula for the volume of a rectangular prism is:

Volume = L * W * H

Where:

L signifies the length of the prism;

W signifies the width of the prism; and

H signifies the height of the prism

In the question we are given:

L = 8 meters

W = 4 meters

H= ?

H = [Assuming it to be: X]

Volume = 64 meters

So to find the height lets plug in all these values in the equation.

Hence:

Volume = L * W * H

64 = 8 * 4 * X

Multiplying:

64 =32X

To solve for X lets shift the number with it to the other side that is divide 64 by 32:

64/32 = X

So:

2 = X

OR

X=2

Hence the value of X is 2 which means that the height of the rectangular prism is 2 meters
