Question

a locker is 1 foot long 1 foot wide and four and one fourth feet high what is the volume of the locker

Answer 1

V = l * w * h

Length: 1 foot
Width: 1 foot
Height: 4.25 feet

The volume = 4.25 * 1 * 1 = 4.25
4.25 cubic feet 

Answer 2

               Volume = (length) x (width) x (height)

(I think you knew that.)

Write the measurements of the locker into that formula:

               Volume  =  (1 foot) x (1 foot) x (4 and 1/4 foot)

                           =   ( 1  x  1  x  4-1/4)  (foot³)

I think I'll leave that multiplication for you to finish up.
