Answer:

10 feet= 304.8cm

70 centimeters= 700mm

15 inches= 1.25 ft

5 meters= 5.47 (exact value) or 5.45 yards

12 meters= 472.44 in

Step-by-step explanation:

10 feet = cm

1 foot= 30.48cm

10 feet x 30.48= 304.8 cm

70 centimeters=mm (millimeter)

1 cm= 10 mm

70 cm x 10= 700mm

15 inches= ft

1 in = 0.083 ft or simply divide by 12

15 in ÷ 12= 1.25 ft

5 meters= yard

5 m = 1.0936133 or 1.09

5m x 1.09 = 5.468065 or 5.47 (exact value) or 5.45 yards (round off value)

12 meters= in​

12 m = 39.3700787 or 39.37

12m x 39.37 = 472.44 in
