Answer:
Step-by-step explanation:
Formula
Volume = L * w * h
Givens
L = 7 feet
w = 4 feet
h = 5 feet
Solution
V = L * w * h Substitute values into the formula
V = 7 * 4 * 5
V = 140 cubic feet.
Answer
140 ft^3
<u>Answer:</u> The wavelength for X-rays with the given frequency is 
<u>Step-by-step explanation:</u>
To calculate the wavelength of light, we use the equation:

where,
= wavelength of the light
c = speed of light = 
= frequency of light = 
Putting the values in above equation, we get:

Hence, the wavelength for X-rays with the given frequency is 
Answer:
places.
