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?
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}.
To find out the total length in centimeters, we need to convert all the measurements to centimeters and then add them up.
1 meter = 100 centimeters
1 decimeter = 10 centimeters
Vinicio buys:
3 meters of red tape = 3 * 100 = 300 centimeters
70 centimeters of green tape = 70 centimeters
3 decimeters of blue tape = 3 * 10 = 30 centimeters
Adding them all together:
300 centimeters + 70 centimeters + 30 centimeters = 400 centimeters
Therefore, Vinicio commits a total of 400 centimeters in tape.
