(1) 1 ft³ = 1728 in³
[tex]1 \: ft = 12 \: in \\ {1}^{3} {ft}^{3} = {12}^{3} {in}^{3} \\ 1 \: {ft}^{3} = 1728 \: {in}^{3} [/tex]
.
(2) 1000 kg = 1 metric ton
[tex]1000 \: kg = 1 \: t \\ 1000 \times \frac{1000}{1000} = 1000 \times \frac{1}{1000} \\ 1000 \: kg = 1 \: t[/tex]
.
(3) 5,280 ft = 1760 yards
[tex]3 \: ft = 1 \: yd \\ 5280 \times \frac{3}{3} = 5280 \times \frac{1}{3} \\ 5280 \: ft = 1760 \: yd[/tex]
.
(4) 16 oz = 1 lb
[tex]16 \: oz = 1 \: lb \\ 16 \times \frac{16}{16} = 16 \times \frac{1}{16} \\ 16 \: oz = 1 \: lb[/tex]
.
(5) 2 cups = 1 pint
[tex]2 \: cups = 1 \: pint \\ 2 \times \frac{2}{2} = 2 \times \frac{1}{2} \\ 2 \: cups = 1 \: pint[/tex]
