Explanation:
The formula for the volume of a rectangular prism is given by:
V=a*b*c , wherea stands for the length,b for the width andc for the height of the prism.
With
The volume is
V=40.5*8*15.75 =>V=5,103 ft.^3
Or, so as to drill fraction multiplication, we could do in this way:
V=(81/cancel(2))cancel(8)(63/cancel(4))=81*1*63 =>V=5.103 ft.^3
