回答1:

假设纸的厚度为0.1毫米,计算得出30次后107374182毫米,
换成米除1000等于107374.182米,除1000等于107.374182公里,
公式为0.1÷1000000×2^30 ≈ 107.37 千米.
以下为每次对折后的厚度,单位毫米
0.2,,
0.4,,
0.8,,
1.6,,
3.2,,
6.5,,
12.8,,
25.6,,

回答2:

折一次,层数扩大二倍,30次扩大2的30次方即1073741824层.
1073741824*0.1=107374182.4(毫米)
=10737418.24(厘米)
=1073741.824(分米)
=107374.1824(米)
107374.1824米>8844.48米
答:是107374.1824米,比珠峰高。

回答3:

每一次对折都会是上一次对折的倍数。那么数字就大了。(我说的是厚度)
第一次对折:0.1×2=0.2mm
第二次对折:0.2×2=0.4mm
……
第五次对折:3.2mm
……
第十次对折:30.72cm
……
第20次对折:0.312km
第25次对折:大约10km
第30次对折:大约320km
第31次对折:640km
第32次对折:1280km
第33次对折:2560km
……
(不信你们去试试,但是劝你们别试因为很费手,而且你又折不出来)

回答4:

因为0.1毫米折一次为0.2毫米,第二次为0.4,所以为0.1(2^30)=1073741824毫米=107374.1824米

回答5:

2的30次方
107374182.4毫米
算成米的 话
107374.1824米
珠峰大概8000多米吧
