Vinicio goes to the store and buys 3 meters of red tape, 70 centimeters of green tape, 3 decimeters of blue tape. How many centimeters does he commit in total?

Answer 1

To convert meters to centimeters, we multiply the number of meters by 100, since there are 100 centimeters in 1 meter. In this case, the red tape measures 3 meters, so it measures 3 * 100 = <<3*100=300>>300 centimeters.
To convert decimeters to centimeters, we multiply the number of decimeters by 10, since there are 10 centimeters in 1 decimeter. In this case, the blue tape measures 3 decimeters, so it measures 3 * 10 = <<3*10=30>>30 centimeters.
Adding up all the measurements, we have 300 centimeters + 70 centimeters + 30 centimeters = <<300+70+30=400>>400 centimeters. Answer: \boxed{400}.
