It is given:A shipping crate carrying e-readers has a length of 20 feet, a width of 7 [tex]\frac{1}{2}.[/tex] feet and height of 8 [tex]\frac{1}{2}.[/tex] feet .
Volume = Length x width x height.
Substituting the values : Volume = 20 x[tex]7\frac{1}{2}times 8\frac{1}{2}.[/tex]
= 20 x [tex]\frac{15}{2}.\frac{17}{2}.[/tex]
=[tex]\frac{5100}{4}.=1275.[/tex]
Volume of Crate is 1275 cubic feet.
