Question

Help me plz

Ivan is 162.4 centimeters tall and is building a tower out of cans that he wants to be as tall as he is. He wants to know how many cans he will need, but he forgot to measure the length of 1 can. He knows that 10 cans are 56 centimeters tall. If he starts building the tower of cans on a stool that is 28 centimeters tall, how many cans does he need for his tower?

Answer 1

Ivan will need 24 cans. 56/10 = 5.6. Each can is 5.6 cm tall. 162.4-28 =134.4
134.4/5.6 = 24
